M-I-C See you real soon. K-E-Y Why? Because we like you! M-O-U-S-E. Mickey first came on the scene in 1928 in the famous Steamboat Willie (which you can still view on Main Street in Disneyland). Mickey has appeared in over 130 films and is most acclaimed as the face of Disneyland. These sets feature fun character designs. The first set has Mickey and his friends on the front of the top with solid color bottom shorts. The second set is an all-over Mickey Mouse and friends striped print with pant bottoms. Both tops are short-sleeved and tagless for a comfortable neckline. Made of 100% cotton and NOT FLAME resistant, so the pajamas should fit snugly.
