That one looks similar to a Frankie Hayes mitt that I did a couple of months ago for the father of one of the kids on my 9 year old team. That one wasn't quite so "inflated" as this one though.
Well, I'll say this much....I have a Goodyear Harry Brecheen 40's split finger posted on JD's incredible site. No doubt about it....it's a Wilson glove....and a nice one to. I would guess that this catcher's mitt is also made by Wilson. I would love to set up behind the plate with it and see how well it performed. I bet you don't feel much pain catching one of those Joba Chamberlain fastballs with this baby.
