Dual Patent 1,509,312 and 2,026,082
In 1940, Parker Brothers closed their office in London and removed the city from the box. This was replaced by Chicago. This is a very hard to find variety, with Chicago AND the dual patent because the Magie patent (1,509,312) expired in 1941 and had to be removed, so this version was only printed in 1940.
