16.25 inches across. 12.5 inches top to bottom. This is an authentic 1973 antique/vintage Mexican Theatre Lobby Card Poster. These were not made available to the general public. These were displayed in the front of a cinema or theatre. Stored in a smoke free environment. I have many other rare antique/vintage posters, banners, flags, and clothing for sale. If there is something in particular you are looking for, please let me know; I might have it and haven’t listed it yet.
