This set of 313 stickers (on 198 cards) offers an addition for 1988--66 different players are pictured on the backs of the sticker cards. The stickers come in two sizes (2-1/8" x 3" or 1-1/2" x 2-1/8"). Larger stickers fill an entire card, smaller ones are attached in pairs. A 36-page sticker yearbook with Mark McGwire on the cover has a designated space inside for each sticker, with one page per team and special pages of 1987 Highlights, World Series, All-Stars and Future Stars. No printing appears on the full-color action shot stickers except for a small black number in the lower left corner. Stickers were sold in packs of five (with gum) for 25 cents per pack. Unlike the 1987 Topps Stickers set, different pairings can be found, rather than the same two players/numbers always sharing the same sticker. - 2007 Standard Catalog of Baseball Cards, 16th Edition.
