She's a unique artist, and you can see her work here (and can even contact her from her website. She's very friendly... ) No, this below is not the commissioned work for the Special Olympics. It's from the homepage of her website.
I've mentioned one of her brothers here a few times in the past, Peter, most notably for his picture in a hard hat on the field at Wrigley Field during remodeling construction before last season began, which has prompted him to suggest that he's responsible for the Cubs winning the World Series after 108 years. However, Diana insists that he has the story all wrong. After all, she notes that she was commissioned in 2015 (the year before the World Series season) to design one of her "Charity Horses" for the Chicago Police Department's 19th district station, which is only four blocks from Wrigley Field. And after the artwork was presented to the station, which is situated in the Cubs' own precinct, the Cubs on the World Series, which is why she claims that she is the person responsible for the victory.
(That's her to the left of Ald. Tom Tunney -- who commissioned the work -- at the presentation, substantiating her claim as evidence that the victory horse replaces the cursed goat.)
Another of her stable of three Honor Horses (made on behalf of fallen Chicago police officers) sits in Mayor Rahm Emmanuel's office.
