Superman's Pal, Jimmy Olsen #77

When Titano returns and snatches Lucy Lane, Jimmy takes an enlarging compound and puts on a duplicate of Colossal Boy's costume to subdue the giant ape. Just at that moment, Allura -- Jimmy's former flame and ruler of a giant world -- arrives and proposes marriage. But the enlarging compound wears off and Jimmy reverts to normal size, so Allura returns to her giant world with Titano in tow.
