According to Heritage Auctions:
"Our December 2012 Auction #7064, Heritage sold the White Album #A0000023 for $13,750 (Lot 46242) after quite a battle between seven bidders. How much more important is this offering? A MT 10 album sleeve with the number you never thought you'd get to see is now available to some lucky bidder. Included is the original poster and four individual photos along with a set of two EX 7 records (not original to this album). Also included is a very informative handwritten Letter of Authenticity dated April 2, 1989, from Clifford J. Yamasaki of Let It Be Records in San Francisco."
Got an extra $20,000-30,000 grand? That's what I think it may go for (if not more!)
