There were plenty of humor magazines before Mad, like this one. Here's another issue of Hooey, volume 2 number 1 to be exact, from December of 1932
The cover is by Bill Holman, of Smokey Stover fame.
Most of the cartoonists here are unknown, to me anyway, and there's nothing about them I can find online. From their signatures, it looks like a lot of them had writers they credited.
