Here's an extremely scarce 1927 Bustin' Babe's & Larrupin' Lou's Barnstorming Premium with their facsimile autographs. These could only be acquired at the ballparks and fields where Babe & Lou would put on their exhibition games.
This superb example comes directly from The Christy Walsh Family, and is just the second one that I've come across in the last ten years.
