The Master Key: An Electrical Fairy Tale by L Frank Baum. Published by the Bowen-Merrill Company, 1901. Hardcover. First edition. No DJ. Past on color cover. 12 color plates as well as black & white illustrations by F Y Cory in full color. This fairy tale founded upon the wonders of electricity might be considered a venture into the realm of science fiction. It is the story of a boy who, in the course of his experiments with the electrical equipment that fills his room, accidentally touches the Master Key and summons up the Demon of Electricity. Hard to determine which printing this is. This does have the space between the (n) in Brooklyn and the comma. But it does have an old gift inscription dated Dec 1901.Some rubbing on the cover and edge wear. Internally, there are a few small spots on a few pages, but overall remains a very nice clean copy.
