These stretch tumblers with optic panels and a fine indentation near the top are very hard to find. This vaseline example is the only one I've seen; it sold for $110 at a 1995 auction. Other vaseline (topaz) examples sold in 1999 for $250, $270 in 2004, and $80 in 2012. In 2013 one brought $140.
Yes, water pitchers do exist, though I have no record of sales. This five-piece set is courtesy of Don and Becky Hamlet.
