What is a special-shaped stamp? What are the characteristics?

There are prototype stamps. This set of stamps is very interesting. It can be torn into a circle or a square. According to your preference, stamps can take on various shapes just by tearing off the 1-3 corners of the square. It will be more interesting to stick them on the envelope. As long as the postage and memory are complete, it will not affect the delivery.

There is also a set of stamps similar to this set of stamps. This is a set of 2005-6J Earth Day stamps issued on April 22nd, 2005.

This set of stamps looks like special-shaped stamps at first glance, but it is not. Although there is a circular perforation in the middle of the stamp, there is no postage and mark on the front of the circular stamp. In other words, the circular part of a stamp is not a complete stamp, it must be surrounded by a square frame, so it is not a set of circular stamps.

This is what makes it interesting. Because postage and stamps are on the square frame, if you tear off the circular pattern in the middle and leave only the frame of a stamp on the envelope, you should be able to send it. It's really interesting.

Although this set of "Earth Day" is not a special-shaped stamp, it is indeed another stamp related to "special-shaped"-a stamp with special-shaped perforations (note the four-corner star-shaped perforations marked with red circles in the picture).

Special-shaped perforated stamps refer to non-circular perforated stamps. The picture on the left shows the first set of special-shaped perforated stamps issued in China. 65438+ 1998- 15 was issued on1June 27th, 998, and a set of three He Xiangning traditional Chinese painting stamps. Note that the place I marked with a red circle is a flat circular perforation, one on the left and one on the right. If you don't know, you may think it's a tear and perforation.
