The Pittsburgh Cultural Trust has postponed an exhibition by cartoonist Ed Piskor, after a woman posted messages she claims were sent to her by Piskor in 2020, when she was 17 and he was nearly 40.

Comic book artist Ed Piskor, best known for "Hip Hop Family Tree" and "X-Men: Grand Design" as well as being the cohost of YouTube talk show "Cartoonist Kayfabe," died Monday, his family announced.
