I don’t know how much you or others here know about the early Dr. Suess, but he was in advertising. Possibly the first thing that put him on the national radar (or would have, if radar had been invented yet) was an enormously succesful campaign for the “Flit” gun, which sprayed insecticide. It’s what Uncle Sam is holding in the cartoon.
The tag line was “Quick, Henry, the Flit”.
There was even a Marx Brothers movie where a Flit gun appeared.
Common in cartoons too.
