Branch Rickey developed the "Knot Hole Gang" membership in 1917 to encourage more fans to the Cardinals games. This was a kids free pass to attend a game and promote family attendance. It was highly successful. Many other teams soon adopted the practice. Below is a membership card from the 1930's.
Jack Ryan was a former Cardinal player and long time scout for the Cardinals. He was enlisted as an endorser for the "Knot Hole Gang" and "Ryan's Knot Hole Gang" trademark was patented in 1929. Special promotional baseballs, bats and gloves were stamped with this trademark. Below is an example of a "Ryan's Knot Hole Gang" glove.
Below is a different variation. This one is stamped "Jack Ryan Special" "Scout St. Louis Cardinals" it is pretty cool, not a cheap throwaway but large and well constructed. It was distributed by National Sporting Goods of St. Louis. I couldn't find much information on National although the glove has some characteristics of a Rawlings glove with the grommet web.
