For your fantasies or many generations of finishing. A large labeled Escher captured in the wilds of Wisconsin. Very Large 9¾" x 2" x 13/16ths+" Light Green rating on end paper. I was not aware of that color.

I partially lapped it after purchase. It needs about another mm off the top.

This the second largest Escher I have found and only second to the largest. $800 shipping included.
PM with questions if you wish

PS. I took the photos prior to having time to devote to the selling, therefore the date was last month.
