This vintage drink tray is marked ©1976 Seaworld Inc.  There are six inset sections that would hold drinks, each has its own design.  Included designs are dolphins, killer whales, fish, penquins with sea otter and sea lion, flamingos with swans and ducks, and the upper center design reading Seaworld with and overview of the park.  Overall size of the tray is 11 inches by 8 inches.  Each of the drink sections measures approximately 2 7/8 inches across and 3/8 inches deep.  There is some wear along the edges where some of the black paint is missing.  A couple of the drink sections do have a bit of light rust, most of this could probably be removed if you wanted.  Personally I would seal the tray as is with something and hang from a wall for decoration.  The back is painted gold.  There are also some gold colored designs on the front in the corners are along the tops of the inset areas.  This would display well with other vintage advertising trays.
