Doing some research yesterday I came across The Bottle Cap Man
a website devoted to, you guessed it - bottle caps or crowns. The site, run by Kenny Yohn in Kansas City is a great resource for collectors and an amazing source of inspiration.
Kenny has an absolutely massive collection of beer
caps dating back to the 50's, the ones above are only a tiny selection from one of the soda sections. I haven't even looked through the beer ones yet - there literally are hundreds.
I feel a new collection coming on!Images copyright The Bottle Cap Man.
