This is a very pretty post prohibition era glass decanter.   The bottle is marked with "FEDERAL LAW FORBIDS SALE OR REUSE OF THIS BOTTLE” and has the Owens-Illinois Glass Company marking.
 
We know this bottle is dated sometime between 1933 and 1966.  National Prohibition ended in 1933, but some states maintained statewide temperance laws. Mississippi was the last dry state in the Union and ended prohibition in 1966.
 
With the stopper, this decanter measures approximately 4" at the widest point and 11.5" tall.
