The Imperial Grape pattern started production in 1912 in crystal then around 1920-30's introduced the colors including the Helios color.  There was some reproduction of the Imperial Grape using the original moulds in the 1950's with the IG trade mark.  Now all the reproduced did not have the IG mark, plus I couldn't find that the Helios color was reproduced.  With that being said, I believe this to be produced prior to 1950's.  The round shape and decorative handles make it a perfect addition to any Mid-Century Modern collection. Helios Green color will add a pop of vintage charm to your kitchen or dining room.The pitcher stands approximately 8 inches tall to the spout and is about 8 inches wide from handle to spout. It has a stippled-glossy finish and is made of fused glass material. This original piece is hand wash only and comes unboxed. Don't miss the opportunity to own this discontinued item from Imperial's grapevine product line.
