A broiler or bake tray in the blue "Cornflower" pattern with metal and wood handled serving caddy by Corning Ware. The tray measures 16" and 10 1/4". The tray is pristine, with no chips, flakes, or hints of use.
From Wikipedia: Corning Ware's range/oven-to-table service first featured the blue 'Cornflower' pattern decoration, designed by Joseph Baum, an artist at the Charles Brunelle Advertising Agency in Hartford, Connecticut. It became the trademark of Corning consumer products for three decades.
