Your dead on Daryl. With 1/2 in holes, the company must have had thoughts of mounting these on a building. (that is a large hole for just a tire rack or something), Like I said on another post, there are small chips on several of the 1/2 in holes on mine and definitely were used. For what I don't think we will ever know. I offered a case or two of beer at Iowa GAS to anyone that could produce a picture of this sign mounted - no takers. My sign had to be mounted with the small chips right beside the holes but it is a mystery that no photos seem to exist of it in that state. Guess I will just look up on the wall and always wonder. My dad's tire racks in his Texaco stations with the BIG tires of the 50s never would have been wide enough for this sign. Just like my car and gas collection - if only they could talk what stories we would hear. Thanks to all. Rob
