The Clarice Krieg 12 Days of Christmas collection (1949-2001) started in the 1950s when library cataloger Clarice Krieg began to collect Christmas cards and other ephemera with the theme of the Renaissance song, "The Twelve Days of Christmas". She continued this collecting until making a gift of the cards and other paper representations in 1999. The collection contains over 1100 examples, carefully cataloged by a classification scheme invented by Miss Krieg.
