New Zealand artist John McNamara provided sporting portraits and illustrations for articles featured in Sports Digest during the 1950's - 1960's. At the time he was living in England and employed as a cartoonist by Amalgamated Press as well as working on various newspaper strips, most famously Francis Durbridges' Paul Temple. On some occasions McNamara's illustrations are credited as reprinted from UK publications but I suspect he was also providing work via the mail for the New Zealand published Sports Digest which was edited by Wellington journalist Brian F. O'Brien from 1949 to 1979.
McNamara's compatriot on Fleet Street, Neville Colvin, also had spot illustrations featured in Sports Digest.
I'm convinced there are a lot of comics, cartooning and illustration work by McNamara that are now forgotten or weren't credited to him. I'd love to hear from any of his family members that might be able to provide clearer picture of his career in England.
