English: Scan via Heritage Auctions. Cropped from the original image.

English: The poster was illustrated and signed (in the top right corner) by Sergio Gargiulo. Although this particular scan does not include a copyright notice, others (e.g.) bear the following notice: "Copyright 1946 Twentieth Century-Fox Film Corp."

English: At least some copies of the poster bore a copyright notice, as described above. However, the copyright for the artwork was not renewed, as was required by American copyright law to extend/maintain protection for works published 1963 or earlier. In order to maintain copyright protection, the poster would have had to be renewed 28 years after publication, in either 1973 or 1974 (see the sections for "Artwork: Original registrations and renewals" and refer to the links to search the copyright catalogs for those years). Because it was not renewed, copyright lapsed at that time. Note that the poster art is a distinct work from the film it represents and had to be renewed separately.
