Does anybody have some history on a Zimmerman's Store in Wentworth, SD? I have what looks like a clay mixing bowl and inside on the bottom of the bowl it says "Zimmerman's Store Speaking, Hello Everybody, Wentworth, SD, 1883." It's tan/beige with two blue stripes around the outer rim and a brown flowery design within the two stripes. Just wanted details either on the store or bowl....my grandparents lived in Wentworth, SD in sometime between 1915-1930. Thanks.
