I recently found an ad in a 1950 issue of Maclean's that solved a Harlequin artist mystery. Earlier this year I discussed an artist who signed his two Harlequin covers as "NMR". And here I discussed an artist who signed his work as "Ralph". I speculated that this was Max Ralph. Now I know the two artists are N. Max Ralph. The Maclean's ad notes that the art is the work of "N Max Ralph" and the signature is clearly the same. There is also a third signature - "R". Why three different ways of signing his work? Here are examples of each plus the ad.
