He wrote a book in the 70's called 'Practical Impossibilities', which you might find at some of the dealers who specialize in old books (some real cool stuff in there on his handling of Marlo's Eidectic Change)and you might catch a few sets of his various lecture notes there as well. Failing that, your best bet (and IMHO some of his best material)is his old 'Come A Little Closer' column in Linking Ring. Pop for the CD-Rom version of LR because he did a ton of those columns in the 70's and 80's. He also did a couple of one-man parades in LR during the 70's, too, that boasted some stellar stuff. I did his no-sleight card in mouth from one of the parades for years and years. I was, needless to say, a big fan and would venture to say that my early exposure to a stack of LRs containing his column shaped my thinking (in that close-up need not be confined to coins and cards but rather any odd toy, container or other piece of whimsy one might find at the dime store)forever. Plus, he made me laugh my ass off. Happy hunting; it's well worth it.
