What's that box?

This is a the Campbell's Tomato Soup Can from Andy Warhol. I have that picture in my kitchen and my dad just loves it. This morning while we were having breakfast he said something like: "I like that thing, it has something really special to it. It represent a whole generation." Dad was actually right even thou he doesn't know much about pop art and all that Warhol movement that came to emmerge after his death.

Next step, Lieschtenstein! I don't if he'll like it but I know I will.
Maybe I should buy him a book about Pop Art.
