An ingenious photographer had a brainstorm about enlarging the art on beer bottle caps, rust and all. There is something about large, familiar items that draws us in emotionally and many artists have capitalized on this phenomenon. Andy Warhol was one of the first to catch on to this trick.
Imagine these prints hanging above your bar. Many have excellent icon art, they are easy to recognize, and certainly deserve more than a quick glance.
I have known several collage artists who collect bottle caps and use them in their mixed-media art works. My kudos to the clever photographer who thought to blow up the miniature works of art. Now, I will study tiny throw aways to appreciate their artistic merit.
