It's A Small World 50th Anniversary Mystery Pin collection slider pin featuring a pair of reindeer from the North Pole section. Sold exclusively at The Disneyland Resort. Total of 16 pins in the set, eight chasers and eight limited release pins. The slider element is the head of the reindeer in the foregound whose head moves back and forth.
