It is the summer of 1933 and the Windy City is hosting the fabulous World's Fair. The famous Navy Pier along the shores of Lake Michigan is invaded by thousands of tourists from around the nation and the world; all there to marvel at the newest scientific advancements on display. But within this glittering pleasure park of wonder lurks a devilish fiend set upon causing mass destruction and ruining the Fair; a scientist turned mad employing a bizarre sonic cannon to commit murder and chaos amongst the innocent throngs. Now it will be up to the unlikeliest hero of them all, the odd, notorious Bagman, to save the day.
Writer B.C. Bell sends his one-time petty crook, Frank 'Mac' McCullough back into action in this, the Bagman's first full length adventure. Along with his loyal buddy, the ace mechanic, Crankshaft, Chicago's most unusual mystery man must find the lunatic inventor and put an end to his heinous attacks before more people will die. Also features a very special cameo by writer Calvin Daniels' own new pulp hero, the Black Wolf. So slap another clip in your .45, straighten your tie and put that bag over your head, pulp fans; here comes the Bagman, delivering justice in his own peculiar way.
