Unmarked, but from the era, and in the style of the Wavecrest, this would be considered a medium size vanity, or powder jar, measuring 3 inches tall, and 5 inches in diameter. There is no lining, and does nor appear to have been any, so may have been intended as a powder jar. The white frosted glass is decorated with hand painted enamel, white flowers and green leaves. The hinged lid has a brass neck, with perfectly working hinge and closure. It is in excellent condition, with just minor wear to the brass finish, and enamel paint.
I currently have several other vanity items in my shop, including other powder boxes, and am happy to combine shipping. To see them all, type the word, "vanity", in the California Girls search box at the top of this page
If you are ordering more than 1 item from my shop, wait to pay until I send back an invoice with the combined shipping discount.
