What does the wrong ticket mean?

Wrong-style stamps refer to some mistakes that do not conform to historical facts, violate science or are inaccurate because of the lack of knowledge of stamp designers, carelessness and sloppy examination departments. These stamps are called "wrong-style stamps". For example, the Columbus commemorative stamp issued by Spain in 193 shows Columbus holding a telescope and looking into the distance, which is not in line with historical facts, because the telescope was not invented when Columbus discovered the new world. In 1847, the British colony Mauritius issued a "black penny" stamp. Due to negligence, the "postage paid" on the stamp was mistakenly printed as "post office". This is the first set of wrong stamps in the world, and the philatelists call it Mauritius post office stamp.

in p>1919, Germany issued an airmail stamp. On the stamp, the plane has neither propeller nor vertical balancer at the tail, so such an airplane can't fly into the sky anyway. It is contrary to common sense that the flag on the Beijing Long-distance Telephone Building, issued by China in 1981, floats to the right in the wind, while the rows of willows and branches in the foreground downstairs float to the left in the wind. The Cultural Revolution ticket "The whole country is red" is also a wrong ticket. Because the map of China on the stamp is not accurately drawn, the sale will be stopped, but a few stamps sold have become treasures. The wrong ticket in Mauritius is even more valuable. In the process of issuing stamps, postal departments all over the world have seen many wrong stamps and made many little-known mistakes and jokes. In 193, the French Ministry of Post issued a stamp, which showed that the peasant woman's sowing seeds with the wind violated the common sense of farming. What is even more ironic is that the figure of the peasant woman naturally falls in the rear when the sun rises. In 193, Italy issued a stamp to commemorate Columbus. On the picture, Columbus looked at the distance with a telescope in his hand, but the telescope reflected in the picture had not yet been invented. ?
