In page Large Münsterländer:

"

The Large Munsterlander is one of several continental breeds of versatile hunting dogs. They are also a HPR (Hunt, Point and Retrieve) Gundog. Although the breed is one of the last of the German breeds to gain official representation by a separate breed club, the Large Munsterlander was recognised as a colour variant of the German Longhaired Pointer prior to that time. The breed first gained official recognition in the Munsterland of northwestern Germany in the early 1900s. However, the forerunner of the modern Large Munsterlander can be recognised in artist's representations of hunting scenes as far back as the Middle Ages. [1]
