For Sale or License
The collection of photos are available for sale in part or in its entirety, including: all negatives, digital files and rights to reproduce the images. My main concern is that someone with the means and knowledge can produce and display the images properly, as well as preserve them. Any of the digital files can be licensed by contacting David Monderer through the Contact page.
