This is sometimes,incorrectly, referred to as a 2 sheet. Often pasted onto wall outside of theater. Later ones were printed on thinner stock. Top four inches were left blank by the printer for the local exhibitor to fill in. Originally made in sets of eight for display in theater lobbies.
Most sets have one title card with production credits and poster artwork.
The other seven cards are colored photographic scenes. Lobby cards are no longer used in the US, but are still sometimes produced for the overseas market. Used in US mass transit systems, mostly in New York. The image is often designed to fit the horizontal format, and is not just an imitation of the US 1-sheet artwork. Not as common as the Quad.
