The calavera above is by Jose Guadalupe Posada, Mexican artist born in the 19th Century. Fantastic artist. I'm lucky to have a rubber stamp with the Calavera Oaxaqueña, dulce!
Spooky, kinda creepy, but also has this great nostalgic feel...like those old, old cartoons from the 30's and 40's. I don't know who created this, but thank you.
