In many ways, the project is a combination of the impulse for economy/reuse with Richter's artistic vision. The process begins with a group of commerically processed 4x6 family snapshots, made by Richter himself or others while on holiday, at his home or studio, or on walks in the park. These are however the images that didn't make it into the albums; they are the duplicates, or marginal compositions, or blurry red eye rejects. The second component is the leftover oil paint, with various colors melded together, smeared on the long plastic blade that Richter uses to scrape paint across his canvases.
Collector's POV: Gerhard Richter is represented by Marian Goodman Gallery (here) in New York. Some of his overpainted photographs have found their way into the secondary market from time to time over the past few years, ranging between $12000 and $25000 at auction. In terms of our particular collection, we need to dig through this book more carefully to see if we can uncover some images that were constructed with with floral or city scenes as the underlying motif, as they would create intriguing contrasts with our existing collection.
