Note the Wildroot Hair Tonic ad in the window (1936). I forgot about Fearless Fosdick. They still make that stuff!
"Fearless Fosdick is a long-running parody of Chester Gould's Dick Tracy. It appeared intermittently as a strip-within-a-strip, in Al Capp's satirical hillbilly comic strip, Li'l Abner (1934–1977)." "Fearless Fosdick is set in an unnamed, crime-infested American metropolis similar to Chicago. Its urban setting stands in stark contrast with Li'l Abner's rural Dogpatch. Fosdick lives in squalor at the dilapidated boarding house run by his dour, pitiless landlady, Mrs. Flintnose."
