that I use for inspiration. The Vine design at the bottom of this post is from here ...It's called "fern motif" by Andre Groult 1913...
Another book that I picked up back in 2001 was at a show in NYC at the Neue Galerie.
The show featured decorative artwork of the Wierner Werkstatte and you can go
One of my favorite artists from the show was Dagobert Peche, and an example of his work is this lovely rose design. The Neue carries books on his work as well as a gift wrap sample book of his wallpaper designs. You can get it here.
