Hi Scott,
I don't know what's more unbelievable...that Mogridge or the Hahn cheque/check. Simply amazing!
Mogridge shouldn't be that tough (d. 1962), but maybe he was ultra reclusive? I've only seen two Sallees, but of course, I have to go up against the deep pocketed 1919 WS collectors (which eliminates Lefty Williams as well, but Dickie Kerr can be had for a decent price every now and then).
Does Mogridge/Hahn fit into a certain theme for your collection? Does it even matter? haha Just gorgeous.
Here's my Hahn/Tannehill/Wiltse. Sorry, I don't have a larger resolution scan available at the moment.
