Hallmark Cards first introduced their Keepsake line of Christmas ornaments in 1973. At first they were mainly glass balls and yarn ornaments. Many of the first pieces were Betsey Clark designs. Hallmark moved away from the glass Christmas ornaments and began creating Christmas ornaments that were figurines and characters. Over the years Hallmark ornaments have been created in designs of Star Trek ships, Disney characters, Harley-Davidson , Barbie ornaments and many other pop culture related designs.
