I don't know anything about Queen autographs but in the description he says its certified by PSA so you should try asking for the cert number so you can verify it through the PSA website here-https://www.psacard.com/
That's absolutely not genuine. Please try to include the band name in your post title next time so that the experts in each field here can have a look for you.
Idk if PSA really passed this or not but PSA gets Queen wrong pretty often anyway. I wouldn't put money down for any COA.
