Fifteen years ago, Chicago artist Dan Grzeca (pronounced Jet-sah) was painting. It was the ’90s, and Bob Hartzell and Steve Walters of Screwball Press introduced him and a slew of other artists, including Jay Ryan, to screen printing — specifically, poster making. “That’s one of the reasons Chicago has such a rich pool of talent,” Grzeca says. “It’s very self-perpetuating with older artists inspiring and encouraging new, younger artists.”
