I found the Postcard Art site[/URL] I have been looking for ages. I was intrigued by the idea of painting postcards on holiday and stamping and posting them to friends. I read an article about George Wittenberg some years go and lost the link. I just found it again on a deep trawl of my bookmarks. His postcards became collectors’ items and his originals sell for amazing sums.
Definitely will check out this link site, Doug, thanks! That’s a popular size that is an easy to mail gift idea, just slip it in a card, apply postage, and voila!
