Los Angeles police continue investigating the theft of 11 Andy Warhol paintings from the home of wealthy businessman and art collector Richard Weisman, according to the LA Times. Leaving no signs of break in and other expensive art untouched, thieves made off with the pop painter’s “Athletes” series, which they can likely never cash in without getting caught. Commissioned by Weisman in the late 1970s, the silk-screened series includes a portrait of himself, as well as ten paintings of sports stars such as Muhammad Ali, OJ Simpson, Pele, and Kareem Abdul Jabbar. Although Weisman is believed to own multiple copies of the portrait series in several colorways, he would still like this one back: an â€œanonymous sourceâ€ has posted a $1 million reward for information leading to the paintings’ recovery.
