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.[mwmfg 4] Magie held the patent until 1935, when she sold it to Parker Brothers for $500,[10] equivalent to $10,672 in 2022.[11] The company had recently started distributing Monopoly, which it purchased from Charles Darrow who claimed to have invented it.[10][3] 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.[3]
