The first packs I bought myself were 1959 Topps Baseball. My folks had bought some packs for me in 1957 and 1958.
Never ventured much beyond sports cards. Even in collecting the Topps 48 Magic Photos and 55 and 56 Hocus Focus cards I stuck to the baseball subsets, except I did do the William Bendix as Babe Ruth card.
I have been sent unsolicited sets of Scream Queen and Dinosaur Attack cards as a "bonus" to other purchases
