Robin Hidden was my art teacher at school. I remember seeing some of his paintings in class – including this one. Some of his senior students were inspired to do their own sci-fi art. I loved it. He often painted listening to the drama on BBC Radio 4.

Thanks very much for your interesting comment, Kevin. On reviewing my posts, I realized that Robin Hidden also created the cover art for “The Great SF Stories 21 (1959)”, which – also with a military theme – features a man instead of a robot. It seems from these two examples that Mr. Hidden preferred to create monochrome or simple backgrounds, placing emphasis on details and color variations in foreground objects. Neat stuff!
