I came across this shabby postcard back in my collection a couple days ago. The dark orange text and the wonderful grungy-ness of the card made me think that it might be useful for you to use in a Halloween project.
The text in the upper center of the shabby postcard back is:
THIS SIDE FOR ADDRESS
The text in the upper right corner is:
PLACE POSTAGE STAMP HERE
DOMESTIC ONE CENT
FOREIGN TWO CENTS
