Rare older double sided Robert Crumb saving Mr. Natural Blotter art Print

Here is a rare print I got years ago and just found when going through some of our files recently. This was not produced by myself or theblotterbin but is a quality older print that I am letting go of now. Snag it before it's gone. Artwork only.
