This is a gallery of grafitti art from various cities. It's called 'Art Crimes' because in most places, painting grafitti is illegal. Many of these pieces no longer exist in the real world. The grafitti art works are from all over the world (Prague - Czech Republic, Munich - Germany, British Columbia - Canada, San Diego - California, Amsterdam - Netherlands) rendering this site truly international. The site also contains links to 'other cool pages on the Web.'
