I am in the Seattle area to! We need to get lunch...Best I could do is probably get a letter of authorization from the Oakley Elite employee that sold them to me. Since its a prototype there are no serial numbers or any other writing inside the arms like production glasses have. The level of quality and manufacturing on these could only be done by a company like Oakley. There is no way any collector could replicate the quality of work done on these. When I took them to my Oakley Vault store in Seattle, they were blown away by how nice and cool they are. When you see them in person, you know right away that they are authentic made by Oakley.
