Determining Authenticity of Flag

[Hoffmavl]

Hi Everyone,

I posted earlier about another flag I was interested in purchasing; however, I have found one for a better buy online. I was wondering if you could tell me if this flag is authentic or not. And would it be too odd to ask the owner of this flag to use a black light to determine its authenticity. I'm not even sure what one should expect to see with a black light test!

Thanks

I could obtain more pictures if they are needed! Thanks again guys.
