FROM 022: Ryosuke Cohen, Japan'Brain Cell 648'

I received this very interesting mailart-piece from Ryosuke Cohen from Japan. It is the number -648- out of the impressive project Brain Cell. For this project Ryosuko Cohen collect stamps, rubber stamps or stickers of different mailartists. He puts the things he receives in a collage on an A3 and send it around the world.
