The deck of cards consists of an "A" and "B" card for each of the 27 presidents included. The A card has the dates of his presidency, his political party and his birth and death dates; the B card lists a varying number of significant events of his life or his presidential terms. Some cards have two presidents on them, presumably because they wanted to include all of them up to the current one at the time of manufacture (Herbert Hoover) while preserving the 54-card deck. —user summary
