I drew this a while ago. Last fall (2009) in Offset class I made some posters. It's a three color print, blue, green, and black. I particularly like how the blue mis-registers with the green in the vomit. It adds dimension.
They're really nice, around 14x17 inches, and on thick, sturdy paper - 'desert sand,' it's called, and is the same paper these were printed on.
