Mr. and Mrs. was a comic strip created by Clare Briggs, which involved the constantly bickering couple Joe and Vi and their young son Roscoe. Roscoe's role was diminished over the years, especially after Briggs died and other cartoonists took over. Here, and in many strips, he serves as an attempt to remind Joe or Vi that they are married and ought to love each other. Joe seems to always have good intentions in his conversations with his wife, but he never really gets it right. In this case he just wants the conversation to be over so he can get back to his radio program. I'm sure he'll care a bit more about the cards after the program is over. Personally, I'd love to send out a card that said "We wish you a comparatively merry Christmas and a happy new year, with certain reservations, and peace on earth such as it is." I wonder what people would think.
