1950s? STATE PLATE of ALABAMA "THE COTTON STATE"

THIS IS AN OLDER COLLECTOR'S PLATE COMMEMORATING THE STATE OF "ALABAMA" AS THE "THE COTTON STATE".  THE FRONT DEPICTS THE STATE SEAL OF ALABAMA AND SEVERAL SCENES, INCLUDING: PITTSBURGH OF THE SOUTH, LOOKOUT TOWER, AND THE STATE CAPITOL.   THE BACK OF THE PLATE HAS NO MARKINGS.  IT APPEARS TO BE FROM THE 1950s, BUT I AM NOT SURE.  IT IS IN GREAT CONDITION -- NOT CRACKED OR CHIPPED.
