That Cubs pennant is the most aesthetically appealing pennant I've ever seen.
This group of items belonged to a semi-pro catcher who in 1911 played against the Kansas City, KS Giants, Leland's Chicago Giants, the Buxton Wonders, and who knows who else. The scorebook is from the 1911-12 seasons, the bat is dated by the label to 1911-15, and the ball is early 1910's.
