Yes I've noticed a definite upward movement in the prices as more and more are becoming ID'd, and people are looking for that retro look. I stall out at a fair once a month and am constantly being asked " have you got any Czech/Sklo Union" mainly by the 25-35 year age group. The vase in Question here is destined as a Birthday Gift for an old friend who is an avid collector and usually helps me with IDing Czech glass, but I felt it a bit unfair to ask him to ID his own Birthday Prezzie!!!
Warmest Wishes,
John
