Additional Info:
measures 17x22. NOTICE: they have the date of 1942 on the bottom. This is currently a hard piece to date for these reasons: 1) the border art matches Cornelius cards issued around 1955 or 1956, but I don't have any cards from the mid-late 1940s to compare to.
2) Paul Henreid's name has (Now, Voyager) which was Henreid's previous film that was released October 1942. I haven't seen this on any other Casablanca poster. Henreid made several other films in the mid to late 40s. Cornelius supplied the secondary market so their material was usually 1 or 2 years after the premiere release. So my guess would either be 1944-1945 OR material pulled from that time for the 1949 reissue putting it 1950-1951 which would be closer to matching the mid 50s borders that we have on hand.
