Valentine's Day
 

Just thinking of the Loveville, MD post office in St. Mary's County, MD. They have special postmark of Cupid. When we lived there and for many years before me, you could have that postmark put on your card for any occasion. Many people sent mail there in a larger envelope to get the cancellation and have resent. Always big write up on it in the local paper.

Got many wedding invitations that way, also.

And the post office is in a trailer, used to share space in a general store.
