What a lovely and elegant duck! Though unmarked, I believe it is Danish Modern, and beautifully made, with an elongated beak perfectly balanced with the elongated body pointed in the other direction, it bears a strong resemblance to the work of Kristian Vedel. I believe the head is birch and the body teak.  What I am not certain of is whether there is an intended function for the opening in the front of the body, which is about the right size to hold a rolled up note to self for safekeeping! 

Perfect condition. 3 3/4" long x 2 5/8" tall x 1 1/2" wide.
