Tough call without provenance. You'd have to check
it against known autographs. Pics of the signing
would be proof positive. If real, could be worth
a lot, I'd imagine. It is entirely possible too,
that the sigs were done by one hand.
Just my two cents.........
They legit guy showed me pics of wild bill,shifty and babe signing the helmet, also checked wild bill auto to the one I have that's psa certified and matches his auto on the helmet, he said he send me copy's of the signing and if I am not happy with it then he trade back without now hassle, he has a 100% trading rating
With all that, it would be a great lid to own
and will only increase in value and interest.
Hopefully the copies of the photos are
high quality prints.........
Yep Steve going to be my prize lid, everyone on that helmet is a true hero and worth what I Gave up to get it which was my m3 flak helmet and a ww1 m1917 helmet with VFW decal on front
