Where to get T207 Blank Back card graded
 

I have one of those rare T207 blank back cards that were floating around about 5 years ago. Has anyone had one of these graded by a grading company? If so, which and/or will SGC or PSA grade these cards these days with an Auth at least?

I don't think they would slab them a few years ago.

SGC should grade it.... at least with AUTHENTIC
