This is an excellent vintage warming tray designed by Russel Wright and manufactured by Appleman's of Bergenfield N.J. It is pictured in the books as a verified Wright design and I have included a photo of this for you. These have been found in a round and in two sizes of this rectangular shape(this is the larger of the two at almost 25 inches long). I have also tried to show in the photos the bent glass which sort of divides the piece making it possible to keep three different food items hot at the same time. This is perfect for a buffet, wonderful on the dining table and the blond wooden handles makes this tray easy to carry anywhere and it keeps food consistently hot even when unplugged. It has been a while since I have seen one of these and even longer since I have actually had one. Very nice condition!
