Paul, Do you know how he "affixed' it to the aluminum substrate?  I tried 
a couple of methods from old books: One was pure nightmare, and left the 
print in shreds. As I recall it used shellac as the binder, but it didn't 
"snap" off the aluminum as promised... it only left in scraps.

The second was more successful.... as I recall a coat of wax which just 
had to be warmed a tad.... but that's from memory. I'll check. (I think 
it's in either P-F #8 or #9 but I'm supposed to be rushing out now, so 
don't stop to check -- lest I end up in the studio instead.)
