It’s four years behind bars for British art dealer Jonathan Poole, who pled guilty to 26 charges of fraud and theft. The 69-year-old, who specialized in selling artwork for celebrity musicians, confessed to stealing both art and money from his high-profile clients for nearly three decades, between 1986 and 2013.

Among Poole’s notable victims was Ronnie Wood, guitarist for the Rolling Stones and a prolific painter who studied at London’s Ealing Art College and will publish a book, Ronnie Wood: Artist, next month. Poole poached a number of Wood’s portraits, featuring fellow celebrities such as Stones frontman Mick Jagger, musicians Bob Dylan, and Ringo Starr, and actress Marilyn Monroe, according to Reuters,

Poole also represented the estates of jazz musician and artist Miles Davis and musician John Lennon. He admitted to stealing works by the former Beatle, as well as works by contemporary German artist Sebastian Krüger and 19th-century French sculptor Auguste Rodin. Most of the stolen pieces depicted celebrities. In some of his scams, he also took a larger percentage than he was due from some of his art sales.

Altogether, Poole, who worked out of two galleries in the Cotswolds in rural south central England, is said to have earned over £500,000 ($664,000) from his illicit dealings. He told the court his business had faced financial difficulties due to Internet competition. Poole was sentenced on Tuesday after pleading guilty at an earlier hearing.

According to the Guardian, prosecutor James Ward compared Poole’s crimes to the 1999 film The Thomas Crown Affair at trial. “[B]oth Thomas Crown and Jonathan Poole stole the paintings in broad daylight,” he said. “Whilst Thomas Crown stole as a challenge because his world had become too safe, Jonathan Poole stole either to fund a gambling habit, or to stash away money for later life.”

Poole isn’t the only art world professional to run into legal trouble with his celebrity clients. In New York, the case between art advisor Darlene Lutz and her former client, pop star Madonna, is currently awaiting a hearing. The singer claims that a planned auction of her personal effects featured objects that were stolen from her by Lutz.
