Dave HornishThat $1,200 is from Mark Murphy's guide, which is six years old. He might be a good contact (bbcardkid on Ebay I think) for values come to think of it. The CU forum might be a place as well. BKB production was probably 5% at most of BB and when you add the OPC angle, there could not have been all that many Canadian wrappers produced for this set.
What I don't know is if wrapper prices are generally heading north or south or if a hoard ever popped up.
Edit-I just found a site that calls it the "holy grail" http://www.vintagebasketballcards.info/main.htm
