Awesome "Frazer Axle Grease" Self-Framed Tin General Store Advertising Sign Circa 1900

This is probably our favorite sign that we own! We picked it up about a year ago. It isn't in the greatest shape, but still beautiful. It measures roughly 48" by 25 1/5". It is an advertising sign from the "Frazer Axle Grease Company". I believe it dates to around 1900-1905, and would have hung in a general store. It is a "self-framed" sign because of the way the tin is wrapped all the way around the wooden frame on the backside. It tells a funny story, look at the picture. We have it hanging in our resstaurant.
