This Bowie autograph was recently obtained from Smith & Sons Collectibles. They claim the provenance was a David Bowie concert in Minneapolis, MN in 97, and provided their own COA.
To me, it has many of the signature characteristics of his autograph at the time, and I believe it to be authentic. Would love to hear other's opinions on this one.
I've just been on their website - the three Bowie's they have on their are all fake and there are a stack of very poor other fakes too - they are using a signed Pink Floyd Wall as one of their main images on the homepage - again very poor fake as is the Relics they are offering at several thousand dollars. Says they offer a lifetime guarantee, suggest you take them up on that. https://collectible.net.au/
Don't know how people like that sleep at night. Poor fakes at premium prices
