what kind of paper is used for postcards
Example of a court card, postmarked 1899, showing Robert Burns and his cottage and monument in Ayr. A postcard or post card is a rectangular piece of thick paper or thin cardboard intended for writing and mailing without an envelope. Shapes other than rectangular may also be used. There are novelty exceptions, such as wood postcards, made of thin wood, and copper postcards sold in the Copper Country of the U.S. state of Michigan, and coconut postcards from tropical islands.
