This charming Christmas seal from the United States features two young carolers singing holiday songs beneath the festive word “Greetings.” Issued by the National Tuberculosis Association (NTA), the design includes the iconic red double-barred cross symbol associated with the fight against tuberculosis. One child holds a lantern while the other sings from a hymn book, capturing the warm tradition of Christmas caroling. Although not valid for postage, these charity seals were widely used on holiday mail to support public health campaigns. Collectors appreciate them for their nostalgic artwork, social history, and connection to mid-20th-century Christmas mail traditions.
