From this Huffington Post article: Anna Pavlova in a famous picture you've probably seen before. But now in high enough resolution to see the century-old "photoshop" job on her pointe shoes! She was famous for having her photos retouched to make her feet look extra pointy and small, because she got a certain amount of crap for wearing modern-style shoes. This same crap-flinging tendency still exists in ballet, of course, but now it's mostly aimed at inovations like plastics and anything that reduces your pain level. Because dancers are crazy mofos.
Anyway, I just thought this was great.
