Otters in Snow, a booklet of 20 stamps,features four different scenes of the alert and playful North American river otter reveling in winter's white landscape. With original illustrations rendered in pen and ink with watercolor, the stamps are arranged in blocks of four. From upper left and moving clockwise, they depict an otter poking its head -seen in three-quarters profile -from the surface of an icy body of water; an otter sliding on its back, tail first, down a snowbank; an otter chest-deep in a snow drift, facing the viewer; and another otter sliding down a snowbank. In the stationary poses, snow clings to the otters' fur. In the views showing motion, small snowballs race the otters downhill.
