I am running a Mail Art Swap project with a lot of artists all over the globe. Postcard sizes are 4x6 or 5x7(i am receiving larger sizes from some people, so i am leaving that open now) They are scanned and put on my website as an online display with your name and link to your website (if you have one) Soon as i receive a piece from you i will send one back to you.

You can see what i have already received, and details where to send them.
