CORRECTION: AI HELPED YOU DESIGN SOME**I designed all of the athletes (and non-athletes) forming the peace sign (except one: Judo)  before June 2008, which is when I got the copyright registration issued from the U.S. Copyright Office. 98% of them weren't designed using A.I.
Before finding a program to design them I used to hand-draw them, I used to take pictures
of myself in front of the mirror or my window so that I could get their silhouette right.
