Sometimes I just purchase a cover because it catches my eye as did this mourning cover from Sharon Springs, NY with the wonderful blue Double Circular Datestamp plus a Shield in Circle killer. So that the killer can be seen even better, I used the retroReveal site to enhance my scan in black and white.
Sharon Springs is in Schoharie County and was established in 1850.
I think I'll probably be searching now for more Shield killer examples from other US post offices. (August 11: As I was working on the manuscript for an upcoming book on New York State Postmaster/County Cancels, I discovered I already had another shield: Highlands Falls from Orange County. I've placed the illustration at the bottom of this blog entry.)
