I couldn't believe my eyes! Finally someone knew some bio data about one of the true geniuses who worked in comics: UK's scriptwriter James Edgar.
Here's (please scroll down) Bob Lorenzo's comment on Steve Holland's blog Bear Alley:
Jim Edgar was born Thomas Eric Edgar on 29th August 1908 in Newton Le Willows. He lived in Kettering for most of his life but after the death of his wife Jessie in 1994 he went to live in a residential home in Sleights Whitby where he died on 4th July 1998. I am in possession of quite a lot of prints etc from "Wes Slade," "Gun Law," "Garth" and "The Boss" (a football script that Jim wrote for the Daily Express). I will email details of these to Steve.
Jim was a wonderful man who must have been one of this country's most knowledgeable people on the subject of American western history.
