Description:  You are viewing a fantastic retro vintage set of four green glass plates.    There are no marks or labels, but I believe that these are the Anchor Hocking Manhattan pattern salad plates. Also called Horizontal Ribbed.   Please view the pictures and decide for yourself.   If these are Anchor Hocking Manhattan, they are very rare and ca. 1938 - 1941.  The reason they would be rare is that mostly the crystal color was made in this pattern, just small amounts of green were produced.   The other possiblity is the Park Avenue pattern that was producd in the 80's. These plates have a fantastic retro look and would be a unique addition to any vintage glass collection that may be used and displayed.  For a designer look, you could mix and match with the crystal. A fantastic & unique gift!! GL1005TBAS750
