Creation Story
Mary Jane Watson is one of the few Marvel supporting characters whose first-appearance history is structured as a running joke. Stan Lee and Steve Ditko introduced the character as a concept in Amazing Spider-Man #15 (August 1964), when Aunt May first mentions her neighbor Anna Watson’s niece. The physical appearance is delayed across multiple issues. Amazing Spider-Man #25 (June 1965) is her first cameo on-panel, with her face deliberately concealed (by a potted plant, a piece of furniture, or careful panel composition). The running joke was Peter Parker avoiding the meeting despite Aunt May’s constant attempts to set him up with her.
John Romita Sr. took over Spider-Man art with Amazing Spider-Man #39 (August 1966) and had the defining reveal staged in Amazing Spider-Man #42 (November 1966). Mary Jane enters Peter’s apartment for the first blind date Aunt May had been pushing, and Romita’s final page delivers the full-face reveal with the Lee-scripted line “Face it, tiger, you just hit the jackpot!” The panel is one of the most-reproduced images in Marvel’s publishing history and established Mary Jane’s visual identity (red hair, green eyes, specific facial structure) that has been essentially unchanged for six decades.
The choice to delay the reveal for over a year of publishing was a classic Lee-era Marvel technique: build reader anticipation through avoidance, then deliver the payoff with a dramatic Romita full-page. It worked. MJ became one of Marvel’s most-loved supporting characters within a handful of issues of her reveal.
The marriage and the retcon
Peter Parker and Mary Jane’s relationship across the 1960s and 1970s was structured as on-and-off. The death of Gwen Stacy in Amazing Spider-Man #121 (1973) effectively left MJ as Peter’s primary romantic interest, and Amazing Spider-Man Annual #21 (1987) married them. The wedding was one of Marvel’s most-publicized superhero weddings and was treated as canonical for twenty years.
One More Day (Amazing Spider-Man #544 to #545, November 2007 to January 2008) reversed this. Written by J. Michael Straczynski with editorial direction from Joe Quesada, the arc had Peter and MJ make a deal with the demon Mephisto to save Aunt May from a gunshot wound. The price: their marriage erased from existence. The retcon reset Peter to an unmarried state and remains one of the most controversial editorial decisions in Marvel history. Straczynski publicly objected to the direction and requested his name be removed from the final issues.
Subsequent writers have reintroduced Peter and MJ’s relationship across various Marvel eras but the marriage itself has not been restored in main continuity.
Collector context
Amazing Spider-Man #42 (Face It Tiger reveal) is the defining Mary Jane Watson key. Amazing Spider-Man #25 (first cameo) is a secondary key for collectors chasing the technical first. Both trade in the Silver Age Spider-Man tier; #42 substantially more valuable than #25.
Amazing Spider-Man Annual #21 (1987 wedding) is a modern-era key that picked up during the 2000s and spiked around the One More Day retcon as fans invested in preserving the marriage material. Amazing Spider-Man #545 (One More Day) is a controversial modern key and collector demand is bifurcated between readers who want to own the retcon and readers who refuse to.
