Stamps, plural. Catch this?
Other nations had a long tradition of issuing stamps for Christmas. (Check the world’s first, from north of the border and all the way back to the 19th century.) The US Post Office was late to the holiday party. In 1964, they made up for it in quantity, offering four options for mailing cards and letters, left.
This was a new term for me: se-tenant. My older brother was the family’s stamp collector, so he probably knew the term.
When two or more designs are printed on one sheet, as you see from the image, the French term for “joined together” seems fitting. Grafted together on the plate are the top four US Christmas plants: holly, mistletoe, poinsettia, and a conifer branch with a cone. 1962’s red and dark green “Christmas coloration” returns. Not liturgical hues, but I’m sure it was the thought that counted for many Christians.
