Collect my favorite team AIK (only miss a few) and former players cards in NHL.
Also collect swedish HOF. Have 600+ of Forsberg and 500+ of Sundin that is my biggest collections of players.
Also a few other swedes and some old favorites non-swedes as Orr, Esposito brothers, Hull, Mikita.
Old goalies wearing scary masks in 70`s is another collection I recently started.
Usually no problems for me to find cards that interests me :-)
