Is there really a red stamp of Wan Li Mountains and Rivers stamped with the postmark 1974?

This can't be true! A piece of red mountains and rivers (commonly known as a small piece of red) was released in advance in all parts of the country on June 5438+0968+065438+1October 19-23 (the official date is165438+1October 25). At that time, journalists, workers and others found mistakes and reported them to their superiors. But in the end, not all of them were recovered. However, this stamp is a household name, and it is the dream object of some stamp collectors, and its reputation is great. By 1974, will anyone use it to send ordinary letters? What you call a "piece of red" stamp with the postmark 1974 should basically be some commemorative sheets or ticket samples on some stamp maps. The postmark is in the lower right corner of the stamp, and a long side of the rectangle in the middle of the postmark is exactly 45 degrees in the lower right corner of the stamp pattern. Look carefully, the box line of the postmark is a bit misplaced on a thin diagonal.
