I bet they were sold concurrently. Just a hunch with nothing to back it up.
We’ve all seen the pics of stadium vendors selling Pennants. And back then, it wasn’t unusual to see 4-5 different variations being peddled at the same time.
I guess we’ll never know for sure unless a definitive photo surfaces... which is highly doubtful. Almost as doubtful as the Trench CEO recalling it from memory.
