After being 2 weeks abroad I found with the incoming mail-art this box from Jack Latteman (Cascadia Artpost) in USA. Besides the formal USA postage sticker he also included on the backside lots of own postage that looked quite good:
The surprise came when I opened the parcek and found this large and wonderful rubberstamp for the TAM-Archives, but for sure also to use it on outgoing mail:
Thanks Jack, for this wonderfuls surprise. It is very much appreciated. Will need some time to settle after being away for two weeks, and then will start with trying to answer some of the incoming mail…….
