Back when the USPS was profitable—just kidding, I don't know if that was ever the case—or at least when people mailed lots of letters, stamps were a fine art. There are some amazing stamps from the 60s, 70s and 80s. And wouldn't you know it, my great grandmother and mom were both collectors so I recently got to dig through hundreds! These are some of my favorites for their distinct mid century vibe.
