Tim Holtz is an amazing creator of all kinds of scrapbook products that I REALLY want to try!! This is one of them... This is actually part of a set of rubber stamps. He's got tons more that he is launching!
If you are interested at all at seeing some of his stuff, go HERE. He has some really fun demo's on his website, timholtz.com. He does alot of grunging and has a different perspective (I guess since he is a guy maybe?). It isn't your normal pink flowery girlie stuff! :)
