When I saw the very first LP records at my neighbor Walter Slagle’s home in June 1948, all of the records had labels on them with their left and right edges cut and “demonstration only” printed on them. I looked on the internet for years before I finally found a photo of these historic labels. The labels in the photo are located in an archival box in the library of congress. The article associated with this photo mistakenly states that 12-inch discs were given blue labels and 10-inch discs were given green, and this is not true. Even the 7-inch LPs and later the 45s that were manufactured by Columbia used the same genre-related color scheme that was adopted from the 78rpm records.
