This envelope was blogged by Jean earlier this year. She mentioned that the post office wouldn't like it, and added my address to the back. I guess they didn't like that either, as this one never made it, sadly.
The stamp is from a sheet of 20 titled American Art, covering four centuries of art on the continent. It features Mark Rothko's painting titled "No. 12".
I'm a big Rothko fan, and will always go and see an exhibit - the colors are so much more intense and interesting in person than on line, on prints or postcards, on photos, and even on stamps.
