Only info I ever had on it was... its really, really old end of day glass. Bought from a lady at a car swap meet and it was practically forced on me! I didn't actually like it for a long time. I bought it over 10 years ago? For about $7 from memory.
And now after giving it a dust and a clean, I noticed that it may have had gold gilding around the edge..either that or inground dirt LOL
(added note... On the Kralik.com website it looks very similar to the Kralik Harlequin Opalescent on the Kralik Visual Decor Index A thru M )
