Envelopes I sent out in 1980. SOmetimes also to my own address, so those were saved. Others are not traceble since I didn’t document those. It show also some of the first rubberstamps I used in those days.
This rubberstamp is part of the TAM Rubberstamp Archive. Also used sometimes on outgoing mail-art when needed. For more stamps see also: http://tamrubberstamparchive.blogspot.nl/
