Highly Detailed Hallmarked Norwegian Brooch of Shepherd and his Goat by Alfred Halfdan Gjerstrom. This wonderful Highly Detailed piece was made by Alfred Halfdan Gjerstrom who lived from 1895-1960. There is a very clear Hallmark on the back along with the numbers that denote his work, and the mark for silver for Europe. The Shepherd and his Goat appear to be wandering the hillsides of Norway, probably with the rest of the flock nearby. A great piece of history in a Silver brooch marked A.G 830 9. The piece is 2 1/2 inches in diameter.
