Shop/business signs for free download?

[Agent Brown]

I've just posted a link for free SF posters for download

and was wondering if anybody had something similar for shop signs? You know, 'Al's Pawn Shop' or 'AC/DC Electricals' or something? Just to give my buildings a bit more character. I've got a few from Worldworks as part of their Streets of Mayhem range but I could do with more variety.
Photoshop is a mystery to me and I'd rather just nick someone else's hard work if possible. I tried creaing my own but it took ages and they were rubbish.

You don't need photoshop to make signs. Microsoft word does the job just fine. Place a text box, fill it with color, and the add the text in the font of your choice. Simple to do and resizes easily.

There are some really nice posters in there.

I particularly like the B5 PsiCorps and Trek Kang reward posters
