This item is a mallard duck replica originally sculpted in clay, then molds made, then hard epoxy ducks created. Can be displayed outside.  Run in epoxy as a hollow shell.  This version of epoxy is as strong as steel (rated at 42,000 psi).  Realistic enough for the Fort Worth Zoo to install in their "weather room".  A big step up from the cheaper, hunting decoys you find online.  This is a museum quality piece that has to be seen in person to appreciate.
