Fresh from a recent box break, each of these five packs is graded PSA NM-MT 8. These cards were vertical cards, as opposed to the Topps horizontal cards for the previous few years. Also, the cards were a return to a more conservative look after cards featuring more glitz in 1971-72. The 1973 Topps Series 1 contained Aaron, Rose, and Ruth. Also, contained Roberto Clemente who had tragically died in a plane crash while on a rescue mission on December 31, 1972.
