This gallery includes all JKA cabinet images I’ve collected over the past few years (the main JKA page has the set checklist). This is a rare set, but the cards are not one-of-a-kind; there are multiple copies known for some of them. If you have any scans to add, please contact me.
The 3 backs shown all have Chicago addresses. The other back is for a Mathewson card that likely belonged to Leon “Red” Ames.
