About a year ago I got with some artists on Twitter and joined a mail art/postcard project organized by @Art_News/@markpvenema: http://markvenema.com/
Finally I have taken pictures of the cards I received!  I was glad to be apart of this project, it was fulfilling making some fun pieces and receiving a different card from around the world.  One of the rules was to not cover the card/use envelopes.  A goal was to see how the travel weathered our creations.

You can see the cards I made for the project in my "Mixed Media," section located in "Imagery."
