I have a vast collection of signs for buildings, billboards, ect. You might have to re-size to use in N Scale as I made these for my HO layout. Here is the link. http://www.trainboard.com/grapevine/album.php?albumid=721
Another page of signs Here is a new page of signs....feel free to use any of my signs for your layout or buildings.
Thanks for the signs, Tomkat. There are hundreds of them on your link to RailImages. Here is a link to the original thread with the comments and questions. Of course the signs will work in all scale when you resize them. Still, we have two threads. H0 scale forum.

Tomkat has graciously provided business signs for your layout. These are only for your personal use; they may be downloaded for that purpose. Some of the signs may have to be re-sized for your particular scale, but that is not hard to do with your computer. There are some more details in the thread; you can read those here. Thanks to Tomkat for the resource. BTW, this is a bazillion signs; you should find something useful there. Additional search terms building business plackard placard store scenery
