Tom Swift And His Jetmarine by Victor Appleton II Antique Book 1954

Published by Grosset & Dunlap. The Tom Swift, Jr., books were a fun, upbeat, and interesting adventure series published for kids from 1954 to 1971 that promoted science, fair-play, patriotism, and team-work; they were good, positive books. The series served as a sequel to the original Tom Swift series that appeared from 1910 to the beginnings of World War II; Tom and his sister, Sandy, are the children of the first Tom and his wife, Mary Nestor; Tom’s girlfriend Phyllis Newton is the daughter of Tom Sr.’s sidekick Ned Newton (now Uncle Ned to Tom and Sandy); the family home is still located in Shopton along Lake Carlopa, etc.
The Jetmarine, the second great invention of Tom Swift Jr., takes the young inventor into a desperate battle with bold modern pirates who have been ravaging the sea lanes off our southern coast.
