As far as vintage postcard artists go, I've always stated that Brian Gerald and A.R.Quinton were probably my favourites. This has probably been influenced by the fact that their postcards were some of the first I came across, and seem to appear reasonably often. I've also liked those I've found by Jotter, Arthur de Brianski and Charles Flowers, but it's only very recently that I've really had much chance to consider the Lakeland Artist, E.H.Thompson. I think I've always has a couple of his postcards, but this week I was fortunate enough to come across three more. Those I have are all "art colour" postcards and published by Valentine, dating to the mid 1940's.
As always, these postcards and hundreds of others can be found on my vintage postcards web site
