“The Sinister Suitcase,” from Power Comics #4 (last issue,1945) fits my definition of a shaggy dog story. It presents a mystery. What is in the suitcase? We don’t know. It also has a fabulous splash page by talented comic artist Mort Leav that has nothing to do with the story. The story is credited by the GCD to Bill Woolfolk, so if stories like this bother you then you will know who to blame.
