These 2-1/4" x 3-1/4" inch cards take their name from their borders which have a scalloped effect. Fronts have a black-and-white player photo along with a blue facsimile autograph. Backs have the player's name and the card number in light blue ink in a small box at the bottom of the card. While there are only 33 possible players; both Jim Wynn and Hoyt Wilhelm cards are found as #11 while cards of Joe Foy and Rusty Staub as #22. Straight edged proff cards are sometimes found but these were never formally issued; they carry a premium. - 2006 Standard Catalog of Baseball Cards, 15th Edition.
