there was some find of these one sheets as they kept getting listed and got very cheap.
I think the reflection is tricking the eye somehow, its not coming off at all in reality, I can see what you mean, but not n person (odd)
there is some damage to bottom right though, it got a bit crushed or something, so its not 100% flat, but doesnt bother me.
what did the 3 sheet go for out of curiosity?
