@easternklaas can you tell us what is written on it besides the keys? You mentioned a logo and a website. Share some more info about it.
It's not wise to reveal more details about what has been found with the exception of the public address of the paper wallet.
Even if you just have the public address you could go to the police to report it and maybe get lucky that the OP has them over the paper wallet. So I would definitely not share any more details here. What also the OP never said is if there is even a valid private key on there. If it is encrypted this whole thread is completely useless.
