In what year did Hallmark introduce the first manufactured Christmas cards?

Although Sir Cole of England created the first Christmas cards in 1843, manufactured Christmas cards as we think of them today began in 1915 when a struggling postcard-printing company that would become Hallmark published its first Christmas card. It was not long before it created the book-like card that is traditional today.
