On a website that documents Audiocassettes, I also found the covers of my old TAM-Bulletins. In those days (the 80-ies) I worked with audiocassettes a lot, and in the TAM-Bulletin I also mentioned those details. Seems it comes from the Archive of Klaus Groh. Below the covers.

Ryosuke Cohen has been doing his Brain Cells since 1985, and this year the 1000th issue is expected. I estimate that I have about 400-500 of his Brain Cells in the TAM Archive, including that very first one also. Today I decided to write him a letter and use the typewriter for that.
Because Ryosuke always chooses an image for including on his Brain Cell I always make sure he has a lot to choose from on the enveloppe. The traditional envelopes are made as I print stamps from the TAM Archive on a regular basis to send the collection back into the network in a printed form.
