Hello Buddy was a small magazine (4 1/4″ x 5 1/2″, 32 pp.) intended to be sold by disabled veterans during World War 2. It contained jokes, poems, and cartoons, mostly on military subjects; it was published by Service Men’s Magazine in NYC, and subtitled “Comics of War, Facts of Service.”

This copy is undated, but a search shows there were other issues, sometimes with the same cover.

A few samples:
