Funny, I didn't know there were any existing photos of Heironymous Bosch's childhood playroom.
Actually, this is a postcard from the Philipines, depicting of course the quaint old Filipino ceremony of having the hideous, flesh-colored ape man line up the corpses of tourists in front of the gaily painted thresher (which is of course driven by a man wearing the ceremonial "neon green mummy wearing a giant piece of candy corn on his head" garb).
I am, of course, joking. Everyone knows this custom is indigenous to Long Island.
