Vintage Miller Trade Mark Wooden Shoe Stretcher

Miller Trade Mark Vintage Wooden Shoe Stretcher. I imagine this shoe stretcher dates back to about the 1930's or before. It is marked "Miller Trade Mark" and is stamped "O.A.M. Co." . There is a 7 on the top of the shoe stretcher with a 4 under it. It measures 11" long. It is for a right foot, probably for a ladies' shoe. It appears completely functional and in nice overall condition. There is a long crack on the bottom of the stretcher but it would not affect anything at all.. Would make a great addition to any vintage shoe related collection. Or use it as-is for its intended purpose.
