I found this theater herald, for Smalley's in Hensonville, in an antique store in Windham, New York. Note the six digit phone number. It's an 8.5 x 11 inches sheet that when opened shows the Cry Wolf ad.
The herald is printed on both sides of an 8.5" x 11" sheet. Folded in half, the "back cover" would have the theater's information printed on it. Open it up and you would see the full-page spread of "Dark Horror" shown here. Nice use of simple colors for the front cover.
Here’s another terrific pressbook from Tony Rivers’ collection. He says “Just received the 4 page press book to the 1940 release of THE NEW ADVENTURES OF TARZAN starring Herman Brix. It’s for the movie version and not the serial which came out in 1935.”
