About Tom Swift, Jr. - Boys’ series of 33 well-written, imaginative science adventure books published from 1954 through 1971. These followed the earlier 1910-4140-volume Tom Swift series, but are NOT revisions/condensations of the earlier series. They are entirely new plots with new characters, but feature some of the family and friends of the earlier series. So the admired and groundbreaking new inventions of the Jr. series are from a much later era, inspired by the space flight advances then in the works, and in the news of the day. #17 in the Tom Swift Jr. series. Grosset and Dunlap hardcover publication. Copyright 1961. Print year estimate is 1967, based on initial publication date of the last title listed on the rear cover, #29 Captive Planetoid (1967). Author "Victor Appleton II," a Stratemeyer Syndicate pen name for the Tom Swift Jr. series. Very good book with excellent spine and hinges. Blue and white space lab endpapers. No writing/markings. Some corner bumping and a moisture stain at the top blue-inked page block (see pictures). In this one, Tom takes hints from Dr. Frankenstein and builds a robot-like body in which to place brain energy sent to him from space friends. This star-headed body is named Exman, illustrated on the cover of the book, who spends time spying on the enemy, the Brungarians. TS17K
