TAM RSA Postage Stamps

The TAM Rubberstamp Archive started in 1983 by sending out the first sheets into the network Ruud knew then, and is now already 29 years old. Still more contributions come in and only rarely the normal public can get a glimpse of what the archive contains. Several documentations about this archive are previously made, and online a large catalogue is available.

There is now a formal page for the TAM Rubberstamp Archive on FACEBOOK as well. There are complete photoalbums with sets of sheets that were exhibited in the past (San Francisco, 1996, Moscom, 2004 , New York, 2010). The link is:
