Seek expert appraisal: Is it true that a picture in 1968, "China's mountains and rivers are all red"?

Fake, there is something wrong with the perforation, the pattern definition is not high, and it is printed by contemporary high-resolution scanning. As for the envelope material, stamps and the like, it can only show that this is a batch of fakes, so we must be cautious.

I hope I can help you, please adopt it. Thank you.
