Final answer:
The property in Monopoly that was misspelled for over sixty years is "Marvin Gardens."
Step-by-step explanation:
For over six decades, Monopoly's original version contained a spelling error for the property "Marvin Gardens." The game, designed by Charles Darrow in the 1930s, mistakenly used "Marvin Gardens" instead of the correct "Marven Gardens," an actual location in New Jersey. This error persisted through various editions, leading many players to believe it was intentional or a fictional name. It wasn't until the late 1990s that the error was corrected in the standard edition. The misspelling became an intriguing piece of Monopoly lore, causing debates and confusion among enthusiasts. However, the correction finally aligned the game with reality, acknowledging the true location while ending the long-standing typo.
The correct spelling of the Monopoly property is "Marven Gardens."
