Though Saint Valentine was deleted from the Roman Catholic church's calendar of saints by Pope Paul VI in in 1969, people still exchange cards, flowers, chocolates, and other expressions of love and affection on February 14. Valentine's Day cards remain popular with schoolchildren and their teachers, while vintage Valentine postcards from the Victorian and Edwardian eras are generally collected rather than given away, proving, perhaps, that for people who are serious about old paper, love has its limits.
