(vtg 1963) Du Barry Silver Pearl Color

This vintage hair color appears to be new old stock. It has its original box, instruction pamphlet, and paper tag on the bottle. The pamphlet is dated 1963. I have not tried to open the bottle but through my research, I believe that it is constructed like a whipped cream bottle with a spray nozzle. I added a photo from a 1963 advertisement as reference. The interior of the box is lined in corrugated paper, which left a striped pattern on the left side of the glass bottle, as seen in the photo.
The bottle is glass and the color is silver pearl. This would look great in a hair salon!
