Hallmark is a company that makes greeting cards and other things to help people show that they care about each other. The name Hallmark comes from the saying “hallmark of quality,” which means that something is of the highest quality. Hallmark makes a lot of cards that people give to each other, usually on special occasions like birthdays, graduations, and holidays, to let them know that they care. They also make other things, like wrapping paper, stuffed animals, and mugs. Hallmark has a special symbol on some of their items that shows that it is a Hallmark product. That symbol is called a "hallmark".
