Mail Art has been around formally since somewhere in the 1940's when Ray Johnson developed the concept behind the New York Correspondence School. The Wide Walls is a great site with photos and information. There is plenty of imagery on the web if you google "mail art." It's very cool stuff. Here is an example from the Wide Walls exhibit.

To my mind, mail art is all about enjoying the process of making mailable sized art and letting it go. It's also about a response from someone you are corresponding with. Though the term "mail art" does call an image to mind, Etegami is mail art. You could include cards as mail art. Why not? I like to include everyone and that's part of the point of it.
I haven't really done much mail art. It was in the back of my mind simmering and this year I'm going to put my big toe in the water. Enjoy today's video and thanks to those of you who asked me about Mail Art.
