This is an authentic original 1930s Bushkill Products Co. metal beer tray that measures about 12" in diameter.
On the bottom is an impression/ghost image of the graphics on the top, perhaps due to being stored in a stack of similar trays at some point in its history. It has some paint-wear, and there are some signs of rust on the bottom and sides.
