Eddy Hood, Northern California artist. The Pepsi Can is circa 1978. Looks to be gouache and/or pastel on Masonite board with a custom plywood and maple edge frame under glass. It's really amazing work. Check out his giant dominoes installation in Davis, CA online and the Let's Rock dancers made of manzanita wood and auto paint that reside in Chico, CA. Currently he is doing book restorations.
I mean, it's incredible to behold, the Pepsi can artwork. Image size is 24x36 with the frame being a little larger. If it said Warhol in the lower right corner it would be worth $20M.
