Sano Shampooing, Rare, Intact, Vintage, Possibly Antique Belgian Store Display, in French and Dutch

This vintage, possibly antique advertising display for Sano, a Belgian hair shampoo, was discovered at the Marché aux Puces de Vanves. It's rare to find such a piece intact. It measures approximately 11" x 6.5" and contains eight packets of dry shampoo. These packets measure 4 ⅞" x 2 ⅞". I advise against using the shampoo owing to its age. I believe this display is circa 1920s, early 1930s, owing to the absence of listed ingredients on the packets.

***** Condition: Please note the display has condition issues with the most glaring being the damage to the lower right side of the pocket holding the packets. This appears as a roughened rust stain. The cardboard, too, has folds, mostly on the underside of the area that holds the shampoo packets and on the right side of this where an edge buckles outward. The eight packets have degrees of fading with the packets displayed in the front having the most fading.

Please examine the photos carefully and do let me know if you need more as I'll be happy to oblige.

Thank you for looking.
