1970 Esso Power Play NHL Hockey Stickers Stamps Complete Set of 252

This set is very hard to assemble. The quality of this set is best described as used condition. Some of the stickers/stamps are in amazing shape, some have been stuck in an album before and have some residue on the back, some show soft corners and some are a little off centre. The pictures are all amazing just like when they were released. I believe these came in panels, however the only ones I really ever see are loose singles. There are 252 stickers in this set. The album is NOT included.
