vintage crystal clear ice glass paperweight w/ fish, freeform shape

Crystal clear glass paperweight with a free form, textured shape link a block of ice. The fish design is etched with a frosted finish. It measures about 5" x 3" overall.

We can't find a makers mark or signature on this piece, and aren't sure of its exact age or origin. But it's a lovely thing, it really does look amazingly like ice!
