According to USA Today, the former night watch volunteer, who was found not-guilty of murdering 17-year-old Trayvon Martin earlier this year, made $110,100 in bids on eBay.
The painting is of a blue American flag with Zimmerman's signature and the words, "God, One Nation, with Liberty and Justice For All."
In the item description, the user "therealgeorge" writes, "Everyone has been asking what I have been doing with myself. I found a creative, way to express myself, my emotions and the symbols that represent my experiences."
His brother, Robert Zimmerman Jr., has confirmed that the auction is real, according to Florida's Bay News 9.
Bidding on the painting began on Dec. 16 and will end in 3 days. So far, 108 people have placed bids on the item.
