as a native of montana, i was exposed to the art of charlie russell during my childhood. i recall visiting his home and studio when i was 10-11-12(?) it left quite an impression on me and i remember vividly the examples of his decorated envelopes and letters that were on display. i am also very fond of his art because it reminds me of the lovely visits to my grandparent's ranch. i don't think i have mentioned him in any blog posts. if you like western art, google him and you can see lots more.
the envelope is from this site http://www.my-west.com/painting-and-sculpture/2011/11/4/painting-of-the-day-november-4-2011.html
