Not sure if it is still in business, but there was a coffee chain in Santa Barbara, called “Green Star” and of course, they preached environmental sustainability. The logo reminded me of the ones I saw in Moscow, and Leningrad, on the hats of the security men, when I was on a class trip, in the 70s. Curious, I dug in to the history of the company. Sure enough, they were formerly known as “Red Star”.
