beginning in Superman #86. Later in 1954, Olsen received his own series, Superman's Pal Jimmy Olsen. The first issue introduced the Signal Watch, a high-frequency supersonic device that allowed Jimmy to contact Superman in case of emergency. Lucy Lane debuted as Jimmy's off-again, on-again love interest in issue #36. Jimmy and Lucy were occasionally married in "imaginary stories" such as "The Wedding of Jimmy Olsen" (issue #38) and The Amazing Story of Superman Red and Superman Blue! The Weisinger Era Early adventures saw Olsen in a variety of slapstick adventures and strange transformations, such as Jimmy transforming into the giant "Turtle Boy" in issue #53. The stories in the title often featured particularly outlandish situations, ranging from Jimmy being hurled back in time to Krypton before its destruction in issue No. 36 to dealing frequently with gorillas of all sorts. During this period, Jimmy Olsen lived a glamorous life as "Superman's Pal" and even had his own (in-story) fan club. Beginning in 1958, Olsen gained the ability to temporarily transform into the superhero Elastic Lad by drinking a serum. As Elastic Lad, he was an honorary member of the Legion of Super-Heroes. When traveling to the Bottle City of Kandor, Superman and Jimmy donned the secret identities of Nightwing and Flamebird, respectively. He was promoted by editor Perry White to the status of "full-fledged reporter" in issue #124 (October 1969.) Superman's Pal Jimmy Olsen was a best-seller throughout the 1960s; at its peak it was the #4 best-selling comic book with an estimated 520,000 copies sold each month. Reprints from the magazine were also featured in 80-Page Giant #2 and #13 (1964–65). Jack Kirby's Fourth World Jack Kirby's Fourth World storyline began in Jimmy Olsen comics in 1970, with issue No. 134. Kirby began by introducing a secret "D.N.A. Project" to create Mutated Humans for Good, adding "the Hairies" (a group of technology-equipped hippies), superbeings from other planets (proto-New Gods), Intergang, Darkseid, and the WGBS media executive Morgan Edge. Kirby also used the series as a vehicle to reintroduce Golden Age characters that he previously created at DC Comics, such as Guardian and the Newsboy Legion. Before the end of his run, Kirby wrote stories involving vampires, the Loch Ness Monster, and Victor Volcanum, a fire-eating archcriminal. A two-part story featured the comedian Don Rickles. Kirby left the series following issue #148. Superman Family (1974-1982) With issue No. 164 (April–May
