Would like to get some ideas from the gang on the forum about the value of this NOS GRAI-PENN Motor Oil sign. Not much to be found online about this brand, or the sign. This painted tin sign measures 15" wide by 20" high. Excellent condition, with very good color. The large "GRAI-PENN Motor Oil" lettering is embossed. The oil can pictures indicates that GRAI-PENN is a product of the Viscosity Oil Co., Chicago, Illinois and Oil City, Pennsylvania, established in 1892.

Sorry for the weird angle of the sign photo. That's the only way I could take the picture to eliminate the glare from some near-by lights. Thanks in advance for sharing your thoughts about the value of this sign. John
