|1990 Topps Batting Leaders #12|
These special "Top Active Career Batting Leaders" cards were K-Mart exclusives found in 100-card blister packs of 1990 Topps (one per pack). K-Mart/Topps did the same thing in 1989, though the cards from that year had red borders. I guess these things are kinda rare since--depending on the player--some of the cards from this set carry a somewhat bloated asking price on eBay, etc. However, you can probably find a copy of this Lansford for a buck or cheaper.
