Donation by J.F. Chapelle - France
A unique rubberstamp arrived as a gift from J.F. Chapelle (France). He decribes how this stamp was made especially for one purpose: to stamp it once on this special paper. I must say I am tempted to use the rubberstamp, but promissed to resist. The rubber will get a special place in the Archive. Detailed photos see below. Thanks J.F.!
