Shawn,
You can borrow my copy of the book to scan from if you want - but you must promise not to make it all icky with your sticky flaneur fingers.
There may still be a copy of the hardcover at BMV at Yonge and Eglinton ( n.e. corner ) where I bought mine. They have another branch next to the World's Biggest Bookstore.
It has a turquoise cover, costs about $24, and is a catalogue of a U.S. museum's collection of Oldenberg's drawings ( I forget which one ).
