Books I have in my collection from that month:

ACTION COMICS 299 (stories by Al Plastino, and Jim Mooney)
ADVENTURE COMICS 307 (stories by George Papp, and John Forte)
FANTASTIC FOUR 13 (the only Lee/Kirby/Ditko issue, that introduced the Blue Area of the Moon, and the Watcher!)
MAD magazine 78 (Aragones, Prohias, Berg, Drucker, and Jaffee art, that I can recall offhand)
SUPERBOY 104 (Swan/Klein art)
JIMMY OLSEN 68 (also Swan/Klein)
TREASURE CHEST 16 and 17 (oddly enough. A now-obscure anthology series)
