Originally these were created as a give away for my poster collecting friends during the GD50 shows in Chicago.  The original run of thirty was given out but I am still getting requests (every day). So, I am releasing my own proofs for purchase.  Each print measures 8 x 8 and is hand printed on 80lb french Speckletone paper and signed and marked as an artist proof.  Quantities are extremely limited.  Proofs can be purchased here:  http://marcguertincreative.bigcartel.com/product/grateful-tube
