Spotted this at today's Art Deco Fair at the Midland Hotel Morecambe (what a fab day! :hiclp:)
Signed on the base Pentti Sarpaneva Oy Kumela. Kumela was started in 1937, was sold to Humpilla in 1976 and went bankrupt in 1985.
Pentti Sarpaneva (1925-1978) was brother to Timo and father of Stepan, the watchmaker. Pentti was a jeweller as well as designing glass. This vase has a decorative metal collar round the top rim. Stands about 210mm high (8¼") and is around 75mm (3") square. Fabulous design reminiscent of the Troika pottery patterns, and came in a range of colours not just the caramel to clear shown here. Many of his glass pieces seem to include metalwork as well, although some webshops show this vase without its collar - presumably the collar has been lost from those.
Two questions: can anyone put a name to the pattern or range please, and pin the date down for me please?
