I noticed there are quite a few pennant collectors here, which is awesome because I've always loved them myself.

I've always been curious about this but have never been able to find a definitive answer: What is the earliest Yankees pennant known to exist?

The earliest I've been able to find through research is a 1921 pennant, and it sold for several thousand dollars because according to the auction description there are only a handful left known to exist. I was just curious if this is the earliest pennant ever made for the Yankees, or if there were some made even earlier than 1921?

Thanks in advance.
