The Book of Dalby is the first known representative of European book culture. It is also an important witness to post-Viking Christianity. The Book of Dalby contains the four Gospels in Latin in a Caroline script. The book takes its name for the Augustinian convent of Dalby in Scania, part of Denmark in the Middle Ages. It was acquired by the Royal Library of Denmark around 1785.

      The stamp was issued 1973 to commemorate the 300th year of the Royal Library in Copenhagen, Denmark. It shows the evangelist Mark from the Book of Dalby.
