Through the mail I got information that A.J. Ward with his A.J.’s Encyclopedia of Stamps and Philatelic Links, is building a huge website (see: http://www.geocities.ws/stamplink/stamps/links.htm) where you can find all kind of information on Artistamps. I had a look and was amazed on the richness of this place. So many things you will find there when you are interested in Artistamps and related stories. He also integrated the Jas. W. Felter website which went offline; have a look at:
A valuable website and link, and a lot of work behind that too!
