For many years the Billboard was the premier trade association paper for the coin machine industry.  Presented here are scans from Billboard for the 40's, 50,s and 60's.

A movie montage of these scans has been prepared for each decade.  This will make an easy audit of the files.

URLs to each directory are also provided where files may be viewed individually.  The filenames, however, do not indicate the content of the file.  The best approach may be to download the entire directory and view the images with a suitable viewer.
