The 1991 Pro Football Hall of Fame set contains 160 standard-size cards. The set, which includes this year's inductees, was issued in factory sets and wax packs. The fronts feature a mix of color or black and white player photos, with black and gold borders (the photos were obtained from the NFL's extensive archives). The player's position and name are given in a black stripe below the picture. A purple box with the words "Pro Football Hall of Fame" in white appears at the lower right corner of the card face. The backs have biography, career summary, and the year the individual was inducted. The backs are predominantly orange in color and have a picture of the Hall of Fame building at the bottom. The numbering is essentially in alphabetical order by subject. Randomly inserted throughout the packs were coupon cards that entitled the collector to receive a free Hall of Fame Album and free admission to the Pro Football Hall of Fame (offer expired December 31, 1993). The front design of the Free Admission card shows four different scenes of the Hall of Fame.
