Several recent posts have shown unusual covers, so I thought I'd share this one.
I have absolutely no idea why they would have used a Pennsylvania Flag Day cachet on the front of this cover with a US Frigate Constitution (Seattle, Wash.) postmark of June 14, 1933 ... but when you turn it over and see the reverse, the correct cachet appears along with a Seattle backstamp postmark without a stamp, also showing the June 14, 1933 date for Flag Day that year.
