I bought this on Ebay. It looks old, but with glass is is hard to determine the age unless you know something about paperweights. It shows wear like children probably played with it because of all the pretty true shades in it. True red, true green, true yellow, a vivid cobalt and even an opaque pink that really is pink like Pepto Bismol. It is on a white ground. The design itself is a white transfer trapped in a clear gather of glass. The glass itself is quite clear with no discoloration. The base is course ground flat. The grinding is a little off center to make the weight sit level.
