We'll see what others say, but I don't like it!°
I think it is OK - there is a reproduction that comes dangerously close to this type , but it has a totally different reverse ( long polyester threads ) .
Heres a photo of a unissued tropical eagle that i have for comparason. deadeye
Your eagle is quite different from the original posting.
His looks to be on brownish material, which I've never seen, while yours is the usual black.
It looks good to me! The discoloration Sarge brought up is in my opinion just the lighting situation.
Brownish discoloration of the thin black cloth background can happen , and I would even consider it a good sign . Compare the insignia on the upper left to the ones below ..
