This is a vintage decanter that might be glass or it might be crystal.  I honestly cannot tell.  It has a flat bottom, a ridged front design that matches the stopper and a rather unique look.  The bottom makes me think of the Batman logo-without the head.  It looks like it was made to hold something expensive.

The decanter measures 7.00 inches tall and is 9.25 inches to the top of the stopper.  The base is 5.25 inches by 3 1/8 inches (in the middle).

The decanter has no markings and no damage of any kind.
