Here is one of the most cherished titles i now also can offer on http://www.ftn-books.com. I now have two sopies of which one becomes for sale. This is special for me. It shows the importance of Ad Petersen as a curator for the Stedelijk Museum and it shows the many contacts he had with world famous artists. He kept and collected the envelopes of the artists he corresponded with and among them many were art themselves, being true ” Mail art”. Studio Anthon Beeke recognized this and published together with Anthon Beeke and Ad Petersen a selection of over 60 envelopes and published these in the book EEN KLEINE VISUELE KEITELING. The design of the book and the collection of envelopes is sublime. Making this one of the most cherished books in my personal collection.
