Leo the Lion Crystal Paperweight Egg shaped with Astrology sign, 1960’s, Vintage

I had always been told that this was Steuben Crystal, but I do not see any Steuben markings (which can often be the case.) Either way, it is attractive and substantial in weight. Some age, not perfect, but still very attractive. Measures about 3” long There is a flat part of the surface on the underside to keep the egg quiet. I have compared the Lion to others online and this one is different from the others: the number of teeth, the paws, the shape of the snout, legs and tail among others difference. I believe this is a superior quality crystal, Steuben, the last American crystal company.
