Gorgeous color transition on this piece.  There is no sticker or sandblasting identifying this piece, however it can be found in the 1997 Blenko catalog on page 15.  Sandblasting "Blenko" and dates began in 2001 so it makes sense this was not marked as such on the bottom.  Prior to this, Blenko used stickers - more specifically from 1982 through until 1999, which may explain the absence of any sticker as well as time and wear usually caused removal of identifying stickers.  The Desert Green/Topaz color for this pitcher was offered in the 1996 and 1997 catalogs, and strangely the crackle glass was not offered in the catalogs as an option which brings me to believe this was perhaps a small batch or short run or only available in their store.  It's a beautiful piece with an applied Topaz handle and the typical Blenko pontil scar on the bottom.  Will be shipped double boxed - also please see our guarantee below.
