H. Guenkel Original Sidewalk Advertising Plaque

Absolutely lovely patina on this advertising mark that would have been embedded in a cement sidewalk. We were unable to find any info on the company but a simple one-story building that looks like a garage remains standing at the address. The "J. Stortz & Son" on the back is a bonus. The company, founded in 1853, is still in business at 210 Vine Street in Old City.
