Mail to Ryosuke Cohen (Japan)

 One of the last envelopes I sent to Ryosuke Cohen in Japan. He uses the icons of envelopes to make his Brain Cell's Collages and everybody gets a sheet in return.  I was also on the 1st edition, and since then on a regular basis I sent him Mail to be part of his long-run project.  It also means he has hundreds of my decorated envelopes in his collection.
