This is what spacemen on the radio look like...
Journey Into Space ran for 3 original series and 1 remake from 1953 to 1958 on BBC radio. The costumes seen here being worn by the cast for publicity pictures are allegedly genuine prototype suites made for Britain's potential incursions into space. (I'm a little sceptical of that but I'll look into it and report back at some future point).
So successful was the show that there were novelisations for each of the three series, the picture above coming from the back of one of them.
To publicise the start of the second series The Radio Times went with this rather wonderful cover image of the now classic fishbowl style of helmet and rippled suit which must have been so very potent back then. This look and feel for a space suit was in keeping with the thinking of the time and, I believe, left an impression upon some of the designers that would go on to work on future television productions in that and the oncoming decade.
