Hi...I just read your summary about Duff Tweed.
I have an original, "Slaughter House Four", but it's all four on one backing, there were only 2 made.
One was "given" to my mother in 1959, the other was sold for $500 to I believe a Canadian millionare.
Duff was a very close friend of the family, he used to teach me how to draw, but wasn't any good, when he would come and stay at our house.
I know, and have seen, the individual carvings in Washington state some years ago.
I am looking for any and all info on Duff....plz eamail me at:
