Incredible sign! Thank you for posting it Rich.
I'm not sure about Honus in the crowd. I thought that was him at the corner of the dugout holding two bats getting ready to hit cleanup.
Speaking of the crowd, one aspect that may help put a date/time frame on this piece is the two sailors in the crowd on the right. Their uniforms are very similar to uniforms worn by sailors in the early 1900s.
Does the stadium resemble any known ballparks from that period? Ballparks aren't my niche.
