Hello,

I am trying to find anyone who could shed some light on the indentity of these two freeform pieces. I have tried the Blenko Museum and Blenko Archives and they dont identify anything. Please Help! The blue/crystal one came from my parents and they aquired it sometime between the late 1950's - early 1960s.  The second one I just acquired.  Blue/crystal one measures 12-1/2"L x 6"W x 1-7/8"H. Amethyst one measures 13-1/4"L x 6-3/8"W x 2-7/8"H (at the highest point) and has Blenko foil label. Wondering if you can give me any info on these (when they were made, who designed them, and possible worth) as I don't see them in any catalogs. Have more pix if you need them. Thanks for anything you know about them!   Kim
