The Consignment Gap: How a Father and Daughter Moved 200 Fakes Through the Front Door

By prove.art Editorial · · 6 min read

Most art fraud stories linger on the forger’s hand — the brushwork, the uncanny ability to mimic a dead master’s line. The scheme run by Erwin Bankowski and his daughter Karolina Bankowska, of Lawrence, New Jersey, is more useful precisely because it doesn’t reward that focus. Over five years, from 2020 to 2025, the pair placed more than 200 counterfeit works attributed to Andy Warhol, Banksy, Pablo Picasso, and several other artists into reputable galleries and auction houses across the country, defrauding collectors of at least $2 million. On April 28, 2026, both pleaded guilty in federal court in Brooklyn to wire fraud conspiracy and to misrepresenting goods as Native American-produced, a violation of the Indian Arts and Crafts Act tied to their forged Fritz Scholder pieces. What makes the case worth studying isn’t the quality of the fakes. It’s the fact that quality was never really the point.

A paper trail built to survive a glance, not an investigation

According to prosecutors in the Eastern District of New York, the Bankowskis’ operation had two moving parts: the objects themselves, many produced by an artist working in Poland, and the documentation built around them. They created forged gallery stamps — reportedly pressed using pages pulled from antique books — and stamped them onto deliberately aged paper to simulate decades of handling. They generated certificates of authenticity from whole cloth. And when a work needed a history, they supplied one: a private collection that couldn’t be reached, a gallery that had since closed, a corporate collection with no one left to call. Each of these details did the same job — not proving the work was genuine, but making it inconvenient or impossible to prove it wasn’t, within the time a consignment desk is willing to spend.

That’s the mechanism worth naming precisely. The works ranged from a $2,000 cardboard piece attributed to Banksy — depicting an Iraq War protest scene — to a $160,000 landscape attributed to Richard Mayhew, with a Warhol nude-figure piece moving for $5,500 and a Raimond Staprans seascape for $60,000. None of these prices required an institutional-grade authentication process; they sat comfortably in the range where a gallery or regional auction house, working from a signature, a plausible stamp, and a coherent-sounding backstory, could reasonably choose to proceed. U.S. Attorney Joseph Nocella Jr., announcing the plea, put it bluntly: the defendants “painted themselves as purveyors of fine art while selling lies on canvas to unsuspecting collectors.” The canvas, in other words, was almost beside the point. The lie was the product.

Why the consignment channel is the exploit, not a side detail

Auction houses and galleries operate on consignment relationships that were never designed as forensic checkpoints. A consignor brings a work, a story, and sometimes a stamp or a folder of paperwork; the house’s job is to sell it, and its incentive is to sell it quickly and at the highest achievable price, not to fund a provenance investigation on every mid-five-figure landscape that crosses the desk. That is not negligence so much as a structural reality of how the secondary art market has always worked — and the Bankowski scheme is a case study in routing fakes directly through that structure rather than around it. Two hundred works over five years did not require breaching a single security system. They required only that, work after work, the paperwork looked enough like the real thing to clear a desk that had no independent way to check it against the object itself.

This is the same gap that let Elmyr de Hory’s forgeries travel five continents decades earlier: verification centered on the story attached to an object rather than on the object’s own tamper-evident history. The Bankowskis’ innovation, if it can be called that, was simply modernizing the same trick — using aged paper and stamped provenance instead of cultivated relationships with authenticators, aimed at a market segment (the $2,000–$160,000 range) below the threshold where anyone would commission scientific analysis.

What an object-bound record would have actually changed

It’s worth being specific about what would have closed this gap, because “better due diligence” is often gestured at without saying what that means in practice. A forged gallery stamp is only dangerous because nothing independently confirms or denies what it claims. If a work carried a record created at the point of production — cryptographically bound to the physical object itself, not to a folder of paper that can be aged, stamped, or invented after the fact — then a consignment desk wouldn’t be evaluating a story’s plausibility at all. It would be checking whether the object matches a record that could not have been fabricated retroactively, the same way a hallmark or a serial number tells a specific truth a written history can only assert. A “private collection, name withheld” provenance claim becomes irrelevant the moment the object itself carries proof of when and by whom it entered circulation.

None of this requires solving art authentication in the connoisseurship sense — nobody needs a chemical analysis of every $5,000 print moving through a regional gallery. It requires making the paperwork unforgeable at the point where it’s created, so that the burden shifts from “can we disprove this story” to “does this object have the record it’s supposed to have.” The Bankowskis were caught, but only after five years and 200-plus sales — a long run for a scheme whose central weapon was two stamps and some aged paper.

The pattern, again

Sentencing is scheduled following the guilty pleas, with the defendants facing a statutory maximum of 20 years and at least $1.9 million in restitution. But the more durable lesson isn’t about this pair specifically. It’s that the consignment channel — the ordinary, functioning machinery by which art actually reaches buyers — remains exploitable by anyone willing to manufacture a plausible paper history, because plausibility, not authenticity, is what most transactions actually screen for. Until an object’s record starts at creation and travels with the object rather than beside it, the next version of this scheme needs nothing more sophisticated than what the Bankowskis already had: a stamp, some old paper, and a story nobody was positioned to check.
