“Detective Dan: Secret Operative No. 48,” published in 1933, is considered the first modern comic book. It will be on display Saturday at Rupp’s Comics as part of the Fremont store’s 22nd anniversary celebration.

Christopher Rupp, owner of Rupp’s Comics, found the unusual book after being contacted to appraise a comic collection for an estate sale earlier this year.

“I discovered that this is a piece of comic book history, and I feel that everyone should get a chance to see it since it is so rare. It’s not every day that you come across an 80-year-old comic book,” he said.

Detective Dan Dunn was a character inspired by Dick Tracy from newspaper comic strips. Both characters boast a sharp, square jaw, fedora and a habit of fighting with their fists.

The anniversary celebration also will feature comic creators Dirk Manning and Chris Enhot signing autographs and special deals 9 a.m.-7 p.m. Rupp’s is at 335 N. Ohio Ave., Fremont.
