The Moon Maid Illustrated

The Moon Maid is a fantasy novel by American writer Edgar Rice Burroughs, belonging to the Lost World sub-genre.

It was written in three parts, Part 1 was begun in June 1922 under the title The Moon Maid, Part 2 was begun in 1919 under the title Under the Red Flag, later retitled The Moon Men, Part 3 was titled The Red Hawk.

As evident from its name, Under the Red Flag was originally set in contemporary Soviet Russia, with the Bolsheviks as villains; as this was not popular with the publishers, Burroughs transferred it to a science-fictional setting, with the evil Communist-like "Kalkars" taking over the Moon (in the first part) and then the Earth (in the second part, with the help of a renegade Earthman) and being finally overthrown in the third part. (Also the Thorists, villains of Pirates of Venus, are clearly modeled on the Russian Communists.)
