First introduced in the 1910s, half-sheet posters measure 22" x 28" and were displayed inside movie theaters to promote the current release. They were mounted in special displays and used together with one-sheet and insert posters to fully advertise a newly released movie. Half-sheet posters were printed on card stock paper and are half the size of a one sheet poster. They were usually not folded and rolled for shipping to theaters. Half-sheet posters were sometimes folded after printing.
