Hello forum! I was excavating a basement foundation today and found an old Pontiac sign. I was amazed at the depth it was and how well it held up being buried for so long. I found some examples online but I’m not sure exactly what kind of business it was or the era that it’s from. I think it’s 42” wide..Any help would be much appreciated!
