Hi-
This might have been discussed before but I recently acquired a 1913 Spalding baseball guide and when I was flipping through the pages I came across the advertisement scanned below for M101-2s. I was able to purchase my copy (sans covers but otherwise intact) for 5.00, so others might be able to find ones at a similarly low price and add a cool ephemeral piece to their M101-2 collections. Or, if anyone wants to know if certain names are on the list, just let me know (I could not make a better scan).
Yours in collecting,
Alan Elefson
