Orion is a hamlet in Alberta, Canada. The hamlet is located approximately 78 kilometers south of Medicine Hat along Highway 61. You can see wonderful postmark (ruined with machine cancellation) with constellation Orion! Orion is a prominent constellation located on the celestial equator and visible throughout the world. It is one of the most conspicuous and recognizable constellations in the night sky. It was named after Orion, a hunter in Greek mythology. Its brightest stars are the supergiants: blue-white Rigel (Beta Orionis) and red Betelgeuse (Alpha Orionis).
This postmark is perfect match for another Star Trek postcard in my collection, this time dedicated to episode "A piece of the Action". You can see trailer for episode bellow.
