I found the New York Public Library Digital Collections. What a great resource for everyone.
"The site is a living database with new materials added every day, featuring prints, photographs, maps, manuscripts, streaming video, and more."
The images come from the Collections for Designers - Ornament and Pattern:

The Miriam and Ira D. Wallach Division of Art, Prints and Photographs: Art & Architecture Collection, The New York Public Library. "1. Foliage; 2. Foliage; 3. Flowers and foliage" The New York Public Library Digital Collections.
The material in the collections is a treasure chest of graphic and abstract design. I spent a long time just poking about and I have not exhausted the resource yet.
