This is something you'll rarely see on the market! An advertisement prop that was used on the countertop of an art supply store; it's subject being that of "Ivory Verithin Eggshells" which were thin pencils with colored lead sold from the 20's through the 50's. Since that time the name Verithin has been used by Prismacolor. I would date this piece somewhere between 1940 to 1950, as the mark on the bottom is stamped onto the glaze, rather than the later applied gold and red sticker. It was not possible for me to get a clear photo of the mark, but I guarantee that it is there with the double AA's and the words Ardalt and Japan. Ardalt was an American Company imported decorative china from Japan, and a few other countries. This piece measures 5 1/2" by 3" and is 3" in height. Makes a great paper weight for the desk!
