Hockey stickers have been around as a collectible for years. They have been produced off and on by two companies OPeeChee and Panini. OPeeChee no longer produces sticker sets, but Panini has put out albums with stickers for much of the 90s and into the 2000s. There was no set produced in the lockout season of 04/05, but they were produced both the 2005-06 and 2006-07 seasons.
For both companies, the basic set was the same. Each team usually had a two page spread in the album with about 6-10 stickers per team. Many issues also had 'puzzle type' stickers, where two or more were assembled to form an action scene. In the early 90s, Panini introduced foil team logo stickers for the team pages.
