[Conveniently, I don't recall or recognize any of these people.] I think it was last year that I drew these sketches in pencil on a cardboard card. These were taking from some photos from an ultimate frisbee game. I don't recall if they were my photos or from someone else. If it was a pickup game our an end of the summer league season event. the pictures I'm pretty sure are several years old. I believe I was looking for source material to practice different people in action and similar poses. I just scanned it, adjusted the contrast and brightness, and got rid of some stuff that's harder to make out than the dog sniffing someone's leg.
