arriving mail (no mail art at all!) from Heinz Mack (Germany) - unfortunately Heinz Mack has sent me the whole stuff back which I sent to him some days ago, without any comments - ZERO Comment to say - lousy reaction! ZERO thank you and ZERO birthday greetings will go to you ! On the 8th of March he will become 80. I always liked his art work, but now I have to think it over maybe.
