The 1968 set marks the beginning of a 21-year run of Topps being the only major producer of football cards. The two-series set of 219 standard-size cards is Topps' first set in seven years (since 1961) to contain players from both leagues. The set marks the AFL debut of the Cincinnati Bengals. Card fronts feature the player photo over a solid background. A team logo is in an upper corner. The player's name, team name and position are in a colored cicular box at the bottom. Cards for players from the previous year's Super Bowl teams, the Green Bay Packers and the Oakland Raiders, are the only cards to contain horizontally designed fronts. In addition, these cards also have color boders at top and bottom and the player photo is superimposed over yellow tinted game action artwork. The backs have statistics and highlights as well as a rub-off cartoon at the bottom. The cards in the second series have blue printing on the back whereas the cards in the first series had green printing on the back. Card backs of some of the cards in the second series can be used to form a ten-card puzzle of Bart Starr (141, 148, 153, 155, 168, 172, 186, 197, 201, and 213) or Len Dawson (145, 146, 151, 152, 163, 166, 170, 195, 199, and 200). The set features the Rookie Cards of quarterbacks Bob Griese, Jim Hart, and Craig Morton, and (ex-Syracuse) running backs Floyd Little and Jim Nance. The second series (132-219) is slightly more difficult to obtain than the first series. This set was issued in five card wax packs which cost five cents and came 24 packs to a box.
