Thanks, I already sent the pictures to customer service and they confirmed that this guitar isn't a real Gibson.
I was scammed and was my mistake receiving the guitar without taking the time to confirm the precedence (Sadly this guitar wasn't cheap). I will donate it or sell it painting the logo to avoid more scams.
Just as a suggestion, It would be great to have a service online to identify fake guitars analyzing pics using machine learning and some blockchain mechanism to track digital certificates and validate the serial number.
Again, thanks all to help me clarify my doubts.
