White-backed artist proofs are printed by Wizards of the Coast and are only issued to the artist. Artist proof amounts vary between 50 and 70 of each card. Mother of Runes has an AP edition of 62. Many of my popular cards have been completely sold out long ago. The front of the cards are printed as normal but the backs are unprinted/only white. They are unique collectible items and highly sought after by some.
Each card comes signed by the artist. The prices are dictated by popularity, rarity, and inventory--as stock reduces, prices go up on remaining cards.
PLEASE NOTE: ALL MOTHER OF RUNES ARTIST PROOFS WERE SHIPPED TO ME FROM WIZARDS OF THE COAST WITH A SLIGHT DENT IN THE BOTTOM OF THE CARD. THIS IS OF COURSE VERY UNFORTUNATE. WE JUST WANT YOU TO BE AWARE OF THIS WHEN PURCHASING THESE SO YOU KNOW THAT ALL OF THEM HAVE THIS SAME ISSUE. WE APOLOGIZE FOR THIS INCONVENIENCE.
