Peter Elson was one of the best of the Chris Foss lookalike artists. Looking through some back issues of SF Monthly, I discovered that Elson had won one of their painting competitions (Angus McBride was a runner up in the other competition they ran). First prize was £50.
The artwork appeared in 1976, by which time Elson had already made his professional debut. He went on to produce a few tens of dozens of covers over the next twenty years but died at the relatively young age of 51 in 1998. He's definitely going to be the subject of a gallery at some point once I can get some more scans together but I thought you might like to see this early example of his work.
