Philadelphia, Winston, 1959. First Edition. First Impression. A tight copy of Ben Bova's first book. The most sought after of the Winston juveniles. Star Conquerors was the first in Bova's Watchmen series. A collectable title. Near fine with some light wear to the spine tips and corners. Price-clipped. Tips bumped a little. Slight toning to the block, but nothing more than usual. A nice book. Cover art / illustrations by Mel Hunter [5839, Hyraxia Books].
