Very cool, thanks for sharing Hank.
I tried to dig around a bit and came across a 1922 bibliography of The Spalding Baseball Collection, online here:
https://books.google.com/books?id=9U...page&q&f=false
This shows at least two possibilities (there may be more):
Pg 6 Spalding's Official Pacific Coast Base Ball Book 1910-1911
Pg 23 Pacific Association of the Amateur Athletic Union of the United States 1910
I know someone at the HOF that has helped me research a few things - if we reach a dead end here shoot me an email and I can drop her a line.
