I have always wondered about this sign , I don't get the wording Motor Truck Service , it makes no since to me but Truck Motor Service doe's. It could be a dumb question on my part but I don't understand it . The sign is porcelain and marked Walker and Co. Detroit , also what would be the time frame when this was used .Thanks for the help and Thanks to everyone yesterday for the welcome and thanks for the company History on the Westcott Sign I think that came from Rabbitman. Merry Christmas Peter
