Very good. Your source was wrong on one item. You state that Ping Pong rights were sold by Jaques to Parker Brothers in the 1930s. That’s wrong. “Ping Pong” was trademarked by Hamley Brothers, the London toy store, in England in September 1900 and in the U.S. in 1901. Hamley sold the U.S. trademark to Parker Brothers in early 1902. Also, Parker never owned the British rights. As for Jaques, it partnered Hamley but did not itself own the trademark in those early years. For more on the game’s early history, see my book Ping Pong Fever: The Madness That Swept 1902 America.
