Manufacturer: Alfred Knobler?
Vintage paper mache tea tray featuring flowers. The flowers look like poinsettas. It has red inkstamp on backside: Design Patent Applied for Japan, Alcohol Proof. Alfred Nobler trays are usually marked similarly which is probably who this was made by. Very attractive tray; it is old and does have some wear and aging but is still quite lovely. It is 17 long x 12.5 wide. Age estimate: 1920's-30's. 12/10labcs-r
