I looked at someones old tire station items and he has a Firestone add of a large tire rolling though a stage curtain and a man off to the right holding up a white tire. The add is advertising the introduction of the new red side wall and black Firestone tire. The add is in very good condition, what is a good price for this item? He also has a vertical Diamond tires sign also in very good condition. Any help on price would be appreciated.
