Fritz Giesendorfer, a Pittsfield Ill. native, was unknown as an artist during his lifetime. The works here illustrate how he drew what was accessible to him — his family, images from magazines and newspapers, public figures and politicians, and himself — that he used drawing surfaces that show that he wasn’t necessarily drawing to ultimately put them in a frame, from poster board to notebook paper to sketches in books and on materials he used to practice sign lettering.
