Original low/mid 1960's pre-U.L. Lava Lamp U.L. product development lab model For Sale

Hello, I'm excited to bring this original early mid-60's Underwriters Laboratory (Research & Development Dept) pre production, 3-colored prototype lava lamp. Not sure if all collectibles have a true "holy grail" piece... but as a collector of 1977 Star Wars figures, I am very curious to see what people think, say about it.It's made of super strong clear plastics & silicones & measures8"×8"×2.5".IMO, perfectly shaped w/perfect colors.Buyer will also get a smaller U L. (same lab) Orange colored prototype model.Both pieces may end up being the only known samples from the UL labs.The square shaped one is sturdy and stands perfectly on all its 4 sides.Feel free to ask for additional photos.Thank you for looking,Drew
