Disneyland Record Labels

I've always been interested by the different colors and styles of the Disneyland Records label. This page shows the evolution of Disney records (pre-Disneyland / pre-1955) and the Disneyland record label (1955-1980s). Notice how the styles and colors change over the years. Some of the different styles can be attributed to the different pressing plants that Walt Disney used. As for the different colors, so far I have not been able to find any pattern or reason behind them. It makes for a fun variation to collect though!
