Oh wow! You should send it to PSA if you can.
Is that a picture or a scan? In your image it does look like it could be brown but the lighting can play a role in that if it is a picture and too bright. Do you have any other T206 brands that are either black or brown in color where you can compare them side by side?
Who is on the front?
You have a shot and I am so rooting for you
Either way a Lenox is lovely. Good luck and thank you for sharing!
