It looks authentic to me.
+1, it looks good.
Me too. Looks natural. Good IMO.
I'd definitely be concerned re the NEW look of this signature & the fact of old crease lines on the actual photo is evident but looks like this fresh ink was signed over these.
if this was a period signature id expect wear or total loss of the ink in places like that ... for me a real concern too fresh.
It looks like the creasing damaged the ink.
Where is it for sale? I’d like to bid!
Seen this before...looks OK to me.
