Heralds
U.S. Heralds were made from the 1910s to the 1980s or so. Theaters would order heralds by the thousands and they would then hire people to stand on busy street corners and pass them out to all who walked by. Since the vast majority of people looked at the herald for a moment and then threw it away, it is not surprising that not many heralds survive.
Most heralds are a single sheet of paper that is folded in half, creating four small pages. The front of the herald usually has just the title of the movie and images of the stars (like a small poster) and the two middle pages usually have a lot of information about the movie along with more images (and sometimes these images are found nowhere but the herald). The back page is usually blank for the theater to print in their name and play dates, to let people know where the movie was playing and when. Sometimes one or more of the pages were full-color, and often some of the pages were two-color.
The nicest thing about heralds is that they often represent an extremely affordable way to purchase an original item from a classic movie.
