Early Shunk Postcard -- An Uncle Harry Production

Imagine my surprise to find the following item for sale on eBay! A postcard of Shunk said to be printed in Germany and "published by Harry Campbell" -- my great-uncle! I snapped it up right away and shared a copy with Uncle Harry's son James who didn't know how the item came to be. I since learned that many early postcards of this country were produced in Germany. Cousin James and I suspected this to be an early entrepreneurial effort on Uncle Harry's part, and I recently learned that we were correct when I found the following among Uncle Harry's papers:

[The] card was sent to Germany at that time to be used for picture postcards.... Postcards on display and sold in Campbell Store.... It was my venture, I paid costs, and Dad allowed me all proceeds from sale in his store.
