I found a scrapbook of collage in an antique collective in Redwood City, California. Its 150 or so pages are completely filled with these works -- quite a lot of effort. The book was not signed, and the store knew nothing about its origin.
As far as I can tell, it was constructed in the very late 1970s, possibly the early 1980s. The materials are greeting cards, newspaper and magazine clippings and cartoons, jewelry catalogs, wildlife pictures, TV show ads, childrens' books, and other everyday sources.
The pieces presented here have been cropped from the originals. This was necessary to provide adequate detail and reasonable file size.
Circa late 1970s
