An unauthorized and unflattering drawing of Donald Trump nude is on sale and the artist asking more than $1 million for the polemical pastel says she’s been threatened with a lawsuit. But the person threatening California-based Illma Gore may be an impostor.

Gore says a man identifying himself as Michael Cohen, Trump’s famously aggressive and loyal attorney, told her last week she would face a right of publicity lawsuit if the original artwork called "Make America Great Again" sells. The case would be an effort of questionable merit claiming unauthorized commercial use of Trump's likeness.

The artist first described the call in an interview with the arts blog Hyperallergic but provided additional details, including Cohen’s name, to U.S. News.

Gore says the man who identified himself as Cohen called from a blocked number, but that a person with the same voice called about a month earlier with a similar warning.

“The person identified themselves as Michael Cohen,” Gore says. "They sounded official."

The calls came after Gore says she provided Facebook her phone number and address, to be conveyed to a person or entity claiming her page violated the Digital Millennium Copyright Act. She provided U.S. News a screenshot of the form she submitted.

Cohen sternly denied any involvement in a short conversation Wednesday.

“You’re calling the wrong guy,” he said. “Nobody claiming to me reached out, that’s a lie, and I don’t believe you on that either. Nobody is using my name, that’s for sure.”

“This is campaign-related, I don’t really have the time to get involved,” added Cohen, an executive vice president of the Trump Organization.

Cohen referred questions to Don McGahn, an attorney for Trump’s presidential campaign. McGahn did not immediately respond to a request for comment.

“If it’s someone being crazy and acting like them, you’d think they would want to know,” says Gore, whose controversial drawing depicts Trump with a small penis.

Images of the artwork were posted online Feb. 9 and Gore believes the drawing may have inspired a surprisingly vulgar public discussion sparked by a joke later that month from Sen. Marco Rubio of Florida about the size of Trump’s hands.

Trump is well-known for being touchy about his hand size. More than two decades ago he was dubbed by Spy magazine a “short-fingered vulgarian,” prompting him to repeatedly trace his hands and mail them to writer Graydon Carter, with at least one note saying “See, not so short!” Carter recounted last year.

After Rubio raised questions about what Trump’s hand size might mean, the billionaire publicly defended another part of his anatomy during a nationally televised debate in early March. “He referred to my hands – if they are small, something else must be small. I guarantee you there is no problem.” Trump said. “I guarantee.”

Gore’s artwork is on exhibit through the end of the month at the Maddox Gallery in London. The gallery has been helping field bids for the drawing, which is listed for 1 million pounds – about $1.45 million. Gore says an American has offered $1 million.

Lisa Baker, a spokeswoman for the gallery, says in an email “there have been good serious offers and they are going up,” without specifically addressing the dollar amount.

“The gallery has had an overwhelming positive reaction to the work and it has created a great platform for discussion,” Baker says.

About 2,000 prints of the drawing, meanwhile, have sold on Gore’s website for between $25 and $50 each (NSFW link), she says. Though she has reaped significant press coverage, Facebook has repeatedly suspended her access and forced post removals, and eBay has deleted auction pages.

Gore, who says she experienced homelessness in her past, has pledged to give a portion of sales to Safe Place for Youth, a charity for homeless young people.

Gore is a supporter of Vermont Sen. Bernie Sanders’ campaign for the Democratic presidential nomination and isn’t a fan of Trump, whose rallies frequently attract protesters enraged by his plans to deport illegal immigrants and restrain Muslim immigration.

But Gore says she counterintuitively sought to chip away at social stigma against small penises by drawing Trump. And she says another unclothed sketch of a politician is on its way.
