Should the agreement include posters?
Yes, if the poster goes on the door or on the table and it has to say the same as the ad. The print run does not need to sit in the agreement: the file does, and the printing goes with whoever prints.

Yes, if the poster goes on the door or on the table and it has to say the same as the ad. Say where it hangs and what date it carries. The poster announces one menu and the ad announces another. You get the poster file, with the same date and the same dish as the ad.
