her rules. Various versions of the game popped up over the following years under a variety of names, Monopoly, Finance, and Auction being among them. Among the Atlantic City and Philadelphia communities of Quakers, the game was particularly popular with college students and economics professors. Jesse and Eugene Raiford, Quakers in Atlantic City, used household items instead of pawns and changed the properties to those of Atlantic City. With Magie's first patent having expired, in 1923, Magie decided to attempt to regain control by applying for another patent. On September 23, 1924, a second patent was issued to Magie for The Landlord's Game. Adgame Company (Inc.) published Landlord's Game and Prosperity under this patent in 1932. Robert Baron had Parker Brothers design its own version, Fortune, before negotiation to purchase her patents in case the discussion fell apart or she sold to another potential buyer, Dave Knapp, publisher of Finance. Magie held the patent until 1935, when she sold it to Parker Brothers for $500.. The company had recently started distributing Monopoly, which it purchased from Charles Darrow who claimed to have invented it. The company only printed a very small run of the game to secure the copyright. Surviving copies of The Landlord's Game by Parker Brothers are considered by many the rarest of all 20th century board games. Parker Brothers pushed her game aside for Darrow's by 1936. Magie then did two interviews showcasing copies of the original board with The Washington Post and The Evening Star to show that Darrow was not the inventor of the game. In 1937, Carnival was published based on the 1904 version. Parker Brothers published their edition of the game in 1939. In a 2004 episode of PBS' History Detectives (title: "Monopoly; Japanese Internment Camp Artwork; The Lewis and Clark Cane"), the show investigated a game board belonging to a Delaware man, having an intermediate version of a game combining elements of The Landlord's Game and Monopoly. The investigators concluded that this game board was the missing link that proves that Monopoly was derived from The Landlord's Game. In 2019, game designer Tom Forsyth produced a replica version of the game through his company yourPlay. The replica went on to sell 500 copies in 2020. As of 2021, yourPlay is planning to launch a Kickstarter campaign to produce a larger number of copies. Description The set had rules for two different games,
