New Worlds 10, Summer 1951. A little wear to cover - photo available on request - internally bright and clean. Very good overall. Contains: Hydra (Burks), Machine Made ( M'Intosh), Prison Trap (Rayer), Ape (Francis), No Short Cuts (Tubb - first appearance in print) and Spacesuits Will Be Worn, an article by Arthur C Clarke about the need for spacesuits when visiting other planets. Includes a photo of Clarke looking older than he does now!
