Here’s a fun little primer on the muses (which apparently started off as three, and then became nine). If you can’t wait to noodle around and find it on your own, here’s the site’s page on the Amazons. The whole site is about women in Greek myths.
Alright, alright so these aren’t really the three muses. The artist (lil’ monkey) says this is Cinderella, her Fairy Godmother, and Rapunzel (going clockwise from upper left). FG is recognizable as the one who mugged Kate Hudson’s sunglasses from Almost Famous. Rapunzel looks like she needs to get a bit more sleep. Okay so maybe Baba is projecting.
