About the Artist and the Pin:
 In 1927 the Danish Government organized a traveling exhibit of fine Danish Craftsmanship, in order to stir up interest in exports to the US market.  the US press coverage was enthusiastic and hailed Georg Jensen as a leader in a new modernist aesthetic, which became known as the Functionalist movement .  Functionalism was partly expressed through geometric form and lack of ornamentation. One of the Jensen designers who participated in the show was Oscar Gundlach-Pedersen.  He designed  3 pieces of jewelry around that time which reflected the movement, one bracelet and 2 pins (#229 and #230). Pin #229 can be seen on page 108 of the book Georg Jensen Jewelry by David Taylor  (I will happily send a scan of the book page via email upon request.) The pin we have here is #230.

While the pin is very well made, please note that it is petite. Please view the last photo below, to get the size comparison.
