17.25 inches across. 12.95 inches top to bottom. This is an authentic vintage Mexican Theatre Lobby Card Poster. These were not made available to the public. These were displayed in the front of a cinema or theatre back in the day. 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.
