Just a heads up....... George Qua from the former Que Buick in Cleveland OH spoke to me today about a Buick sign that was on their building. Que lost the Buick franchise in '91 and he has 2 large BUICK script (17" high x 70" long)
that were on the building. He does not know what they are made of, I suspect steel. They are not lighted but weigh 22 lbs.
He is going to send a photo which I will post. They were made in 1947 for the new dealership that his father built at the intersection of 103th and Shaker Blvd in Cleveland. I suspect that he will put on Ebay and/or in the Bugle. He thinks they are worth $1,000 each.
