Good price on the Venini book. The Catalague Raisonne reproduces the Catalogo blu, Catalogo rosso, and Catalogo verde, dealing with 1920's-30's the 1950's,and 1921-1969 respectively. Deboni contains the same three but in larger scale. Both have many excellent pictures, with quite a few pieces appearing in both books.
In terms of using the books to recognize pieces to pick up, I'm less sure. My sense of finding Venini is that you need two things, to be able to find the acid mark (not always easy), and lots of money. The books are as close as I'll get to most Venini pieces so that's why I have them.
The full title is Franco Deboni,Venini Glass. Volume 1 is subtitled, Its history, artists, and techniques, volume 2, Catalogue, 1921-2007, which, in fact, consists of photograps of the glass, not the catalgues,which are in the other volume. The book was published in 2007 by Alberto Allemandi. I can't find an ISBN number for it.
