I have five disks with articles/exhibits - pdf on disk - from the U.S. Philatelic Classics Society that I am giving away since I no longer collect U.S. stamps. If you interested in any of these, please send me a private message. Need to have 50 or more quality posts on this forum to respond in order to access the message system. U.S. or Canada addresses only please.
As always, please consider a donation to this forum or StampSmarter to support this great hobby.
