Several of those posters can be found on walls, mostly around the Upper part.. all of them are written on in a delicate small handwriting, but each are individually adorned by drawings of little colorful flowers and the like.. They read:

Cloak and dagger, shield and blade Useful in our trade Magic wands and dweomered rings and other wondrous rare things you can have everything of that galore but don't bother going to the store

buying, trading, maybe selling without the unnecessary yelling that is common on the marketplace where no one has a friendly face

For all your adventuring needs keep an eye out for and take heeds to the merchant Frum Highill and try as hard as you will You will not find a better deal and if you do it is not real!
