The cards in this 525-card set measure 2 1/2" by 3 1/2". The 1972 O-Pee-Chee set is very similar to the 1972 Topps set. On a white background, the fronts feature color player photos with multicolored frames, rounded bottom corners and the top part of the photo also rounded. The player's name and team name appear on the front. The horizontal backs carry player biography and statistics in French and English and have a different color than the 1972 Topps cards. Features appearing for the first time were "Boyhood Photos" (KP: 341-348 and 491-498) and "In Action" cards. The O-Pee-Chee cards can be distinguished from Topps cards by the "Printed in Canada" on the bottom of the back. This was the first year the cards denoted O.P.C. in the copyright line rather than T.C.G. There is one card in the set which is notably different from the corresponding Topps number on the back, No. 465 Gil Hodges, which notes his death in April of 1972. Remember, the prices below apply only to the O-Pee-Chee cards -- NOT Topps cards which are much more plentiful. The cards were packaged in 36 count boxes with eight cards per pack which cost ten cents each. Notable Rookie Cards include Carlton Fisk.
