What Year is it?

[Greg Sealock]

I just found a brass center cap at a local antique store. It is 3 1/2 " in diameter, the center portion is raised and shaped like a stop sign, and "BUICK" is stamped across the center. I bought it for $5 for the heck of it, but all of the old pictures are either in black and white, or the wheels are fuzzy if they are in color that I have been able to find. I am assuming it is from the teens or early twenties. If it sounds famimliar, or if I got screwed let me know.

Thanks,
