I am pretty sure "draw 50" refers to Lee J. Ames' "Draw 50 Somethings" series of wordless instructional books, where "something" ranged from "animals" or "athletes" or "dinosaurs" to "Beasties and Yugglies and Turnover Uglies and Things That Go Bump in the Night". Drawing fifty instances of a thing out of your head is a good exercise but completely different from those.

Oh cool! Yeah it made me think of these internet challenges "I'll draw and post 1 portrait a day for the next year" or whatever. And art classes "give me 20 sheep". Where it's fine to start "literal" but you are encouraged to get bored of that quickly and become more creative with it.
