Valentine's Cards

Greeting Cards
The oldest known greeting card in existence is a Valentine made in the 1400's and is in the British Museum.  New Year's cards can be dated back to this period as well, but the New Year greeting didn't gain popularity until the late 1700's.  The Valentine and Christmas Card were the most popular cards, with Valentine's offering us the most "mechanical", "pop-up" and filigree cards, followed by Christmas,  St. Patrick's Day, Easter, Halloween and Thanksgiving.  Cards gained their highest popularity in the late 1800's and early 1900's offering us cards with some of the most unusual art.  The Victorian age give us the most prolific cards.
