I happened to be on the Mad Magazine website last night (don’t ask, I just happened to be there, OK?).
At any rate, they are currently openly advertising for a new, regular-feature cartoonist position!
I wish I could draw, as the job description is great - you pretty much have free reign to do what you want!
At any rate, if anyone gets the job, thanks to reading this tip, I want an autographed copy of your first published cartoon!
