Hardcover 1st edition. When I saw this in a used book store back in the early 80's I thought the asking price was outrageous at $25.00.
I bought it anyway. Unfortunately (for me) I never dreamed back then that the value would increase so much.
It was in the attic for so long unprotected yet it is still in very good shape except that
the white turned a bit yellow (which I "cleaned up" for posting).
