About Tom Swift, Jr. - Boys’ series of 33 well-written, imaginative science adventure books published from 1954 through 1971. These followed the earlier 1910-41 40-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. #26 in the series. Grosset and Dunlap. Copyright 1965. Rear cover lists to itself. This may be a first edition, but it's uncertain, as many first editions list to the prior title. Very good+, clean picture cover book with minor cover abrasion wear. Black/white space lab endpapers. No writing/markings, no tracking, minimal corner bumping. In this one, Tom has developed a sonic boom noise deadener - it beams out malicious sound wave attacks - which comes in handy when a national sonic boom threat occurs. Tom and Bud are also in Outback Australia with their new robot bloodhound. TS26
