At the start of this year’s baseball season Oakland-based illustrator Sarah Clark found herself with season tickets to the A’s. Seeing so many games in her future she decided to document her summer of baseball through short comic strips called “Season Ticket Diaries.” She’s currently up to her 18th game of the season which documents the August 4 showdown with the Texas Rangers. Clark has been tapped to be the next “Cartoonist-in-Residence” at the Comic Art Museum on September 21. Visitors to the museum will be able to view her illustrations, watch her work, and ask questions. She’ll be at the museum between 1 p.m. and 3 p.m., which also happens to be the same time the A’s will be playing the Minnesota Twins. Be sure to thank her for choosing to spend part of her day at the museum instead of at the ball park.
