Corey Brown over at Artcardist.com surprised me -- on my birthday no less! -- with the news that my gallery page was live. I'm delighted and honored! Stop over and take a look: http://artcardist.com/gallery-2/karen-koch
Be sure to browse the other artists in the gallery; they're wonderful!

Corey also runs a blog about artist trading cards and ACEOs: http://whatisanartisttradingcard.blogspot.com
