Stamp Watermarks
Stamp Watermarks refer to the subtle designs or patterns that are impressed into the paper of a stamp during the manufacturing process. These watermarks are typically translucent and can be seen when the stamp is held up to the light. They often feature intricate designs such as letters, symbols, or images that are unique to specific stamp issues. Stamp watermarks can be used to authenticate and identify stamps, as well as to help determine the age and origin of a particular stamp.
