For a long time I collected crown caps of various beer brands. This collection was gathering dust and I could either throw them all away or do something with them and then throw them away. Digitizing them was the only non-dust catching solution. At first I wanted to make a page for every brand, but hey, a hobby should not become a manic 'have-to-do'-thing. So, nice and simple: 5 images with crown caps, nicely mixed up.
