Thanks for taking the time to look at the Nirvana signatures. I understand your skepticism, but I wanted to share a few important details that might help put things into better context:
– All three signatures (Kurt Cobain, Krist Novoselic, and Dave Grohl) are on the same large-format Nevermind poster (80x60 cm). So the signature are kinda big.
Because of the size, the autographs are quite large, and some lines may appear slower or more hesitant simply due to the scale of the surface.
The poster was given to me by a friend who works in the music industry. He also provided me with a signed Angus Young item, which has already been confirmed as authentic and comes from the same source.
