Advertising Pot Scraper and Bottle Opener

This is a advertising pot scraper and bottle opener. Reads "A remembrance from R. E. Sparks The Grocer stop and shop Sturgis So. Dak. Phone 34" I collect pot scrapers and bottle openers. Most of the ad pot scrapers I have come across are older lithograph tin. This is plated steel. I am think the two digit phone number would date it to the 50's. But that's hard to say because South Dakota is usually about 20 years behind on things like this.
