The Blackhawk Restaurant was in the Chicago Loop area from 1920 to 1984, and this ticket envelope was issued in association with the 1962 release of "How The West Was Won"!! It is in EXCELLENT condition and approx. 3.5" X 4.25" with the flap open as shown!!! It will be shipped via 1st Class Letter Rate to keep the cost down, so there will be no tracking!! Please see my many other ephemera and travel souvenir listings and email me with any questions!!
