For a second year, ballplayer "stamps" were sold in conjunction with team albums. Approximately 1-7/8" x 3", the pieces are printed on glossy paper in full color with a white border and facsimile autograph. Backs, which are not gummed, have gluing instructions and the player's name at the bottom. The 1970 issue can be differentiated from the 1969 issue in the backs do not carry a notation at bottom about using the "Official" collectors album. The unnumbered stamps are checklisted here alphabetically. - 2006 Standard Catalog of Baseball Cards, 15th Edition.
