This 12 inch wood ruler is an advertising piece from Billiken shoes. The front of the ruler has 12 inch measurements and advertises that Billiken- The Wonder Shoe of the 20th Century. The back has no markings for measuring, however it is loaded with advertising. The Billiken shoes were made by McElroy-Sloan Shoe Co in St. Louis, Mo. Slogans on the reverse side of this ruler are "Billiken shoes cannot pinch but are sure to tickle." and "America's Highest Grade Child's Shoe." The ruler was made by F.L. Rand Co. St. Louis, Mo.
McElroy and Sloan were in business in the 1920's and this is a nice old ruler from this era.
