The cards in this 54-card set measure 2 1/8" by 3 1/4". In 1974 the Kellogg's set returned to its 3-D format; it also returned to the smaller-size card. Complete sets could be obtained from the company through a box-top offer. The cards are numbered on the back. Cards still found with the wrapper intact are valued 25 percent greater than the values listed below.
