Re: Does anyone know what this is?
Gobs of merchandising color corrected the shirts in the 70s and early 80s. It was usually done to add eye catching color. Sometimes it was cost cutting/ effective. I had paper birthday plates when the animated series was on depicting most if not all characters in red shirts.
I seem to recall Star Trek The Phenomenon
being the name of a TV special from around the time The Motion Picture
came out. The host talked about the enduring appeal of the show and interviewed Leonard Nimoy. Perhaps, it's a flyer for that.
