Monopoly Sights: "Marvin Gardens," 2007
"Marvin Gardens" was the name that Charles Darrow used in his original 1933 Atlantic City Monopoly game board, but it was in fact a misspelling of the name "Marven Gardens," a small residential neighborhood located near the boundary of Margate City and Ventnor City, just south of Atlantic City. Parker Bros. issued a formal apology to the residents of Marven Gardens for the misspelling in 1995. Some people around there are still sore about it, though.
Although a house in "Marvin Gardens" costs $150 in the classic version of Monopoly, today they seem to be going for upwards of $699,000.
