It has a vinyl cover but there’s a plastic roundel in the middle with Mao’s face (as shown in picture). When I got it the roundel was yellow but in the past few months it has developed a weird red discoloration. I live by the ocean so damp air could be the cause. The roundel looks and feels like a sticker as well so if removing it is possible I may be open to that as well. Does anyone else have the same version of the book as me or would know what’s going on?
Could be that it’s exposed to sunlight and the yellow color is fading, exposing the red underneath? It looks pretty normal for a book to age like that, I personally like aged books, reminds me that the object itself has a story as well.
