Heralds were first used as early as the
1910's. Heralds were essentially 5" x 7" or 6" x 9" one page flyers. Some
heralds were larger in size, and some were more than one page. Printed
as an inexpensive ad flyer, the herald quite often would include a picture
of the star or stars and general Information about the movie. One herald
was normally included in the press
kit, or campaign kit
that was sent to the movie exhibitor.
Heralds were used up until the mid-1970's,
particularly for major promotional campaigns. Below is a 4 page herald
for Shaft that was included in the presskit. Notice that on the back cover
is the printing information where the theater information would normally
be printed.

Heralds are considered collectible but
do not command the same dollar value as do the movie's posters. Heralds
were distributed by the thousands directly to the public, which lessens
their value as a collectible. To a collector, however, heralds are far
more affordable.
In the shake up of materials in the mid
1980s, theaters moved to using mini sheets
and promo cards as mass giveaways instead
of heralds.
