Christmas Cards. They do not really stand out in my memory. I remember my parents send them and we got some, but my mother did not display them prominently.
However, Chuck said his parents always received about 100 cards and they hung them up by tape on the wrought iron railing that was on both side of the steps going up to the second floor.
They kept them in a box and then the next year they would make sure everyone would get a card in return. Chuck remembers every year his parents would have a card and mentioned that the person had died during the current year.
I send cards myself but only to family and a few friends who now live out of state. I think it is the cost of postage that limits the amount of cards that most people send. When Emily was little and in school I would take the best snap shot, make one of those family cards and send them to friends and family. I found that Aunt Edna and the grandparents saved them all.
