During my everyday quest for good old books, I found a nice copy of the 1981 Graphis Diagrams edition for a very low price: around 30 $ and not 250 as usual.
As I don’t want to set a bookshop, I’m proposing for who wants to own this gem to get in touch with me. A small taxe is asked for the effort.
Sorry, item sold. Thanks to all of you who get in touch.
