Last year Dick Tracy made a cameo appearance in Gasoline Alley (Tracy Comes to the Alley). Today Dick Tracy's current creative team, Mike Curtis and Joe Staton, returned the complement. Walt Wallet appears in Dick Tracy, and it's clear he's no stranger to the master detective. (click on image to enlarge)
Vitamin Flintheart first appeared in the Dick Tracy strip in 1944 -- and he was old then. There's a good chance that he and Walt Wallet might actually be the same age!
I wonder if there will be a mention of Uncle Walt's good fortune in Gasoline Alley.
