This vintage Strombergshyttan Swedish etched glass egg features a picture of the Aries ram.  It is 2-1/2" high, 1-5/8" in diameter at the widest point, and features a flat bottom for stability.  I have owned this for at least since the early 1970's and received it new as a gift.  Now I am downsizing my collection, and hope to find a new home for this pretty egg.
