Seventh part of the Guyot opera, which was missing from my other set. This is only the seventh part: in my collection the eight part is (to date) still missing.
The book is in the original wrappers and some pages are detached. It is larger than the volumes I-III as these would have been trimmed on binding, but it is as it was issued by the publisher. Still part of the same edition by Gueffier, so it is part of my set.
Will have to wait until I find the eight part to then bind it (perhaps).
It contains some magic tricks, including the "27 cards trick" (with a presentation similar to the ACANN) and the trick of the three Jacks put in different parts of the deck that come together.
The same book was sold on eBay in November for 53 EUR - I bought it from the American antiquarian for $100 more...
