A flickr with a ton of old magazine ads and clippings in Portuguese. These two pictures are by José Stuart Carvalhais, who, allegedly, is the father of Portuguese comic books. He doesn't only illustrate people with arms akimbo.

(I'm fairly sure I learned the word akimbo in 5th grade, from the book Roll of Thunder, Hear My Cry, and I always get excited when it's even remotely appropriate to use in a sentence (about once a year))
