We first met artist Wes Chapman here with three covers he did for Export Publishing Enterprises. His signature is also seen on six Harlequins from 1951 and 1952. Here are the first three.
Wes Chapman (1929 - 1995) signed three covers for Export Publishing Enterprises, a Canadian paperback publisher in the late 1940s and early 1950s.
Chapman has a listing in the Index of Canadian Illustrators and examples of his work can be found here. An interesting discussion board about Chapman is here.
