A simple Modernist art glass vase, probably designed by Tamara Aladin. Made by Riihimäen Lasi Oy / Riihimaki, Finland. It has the model number 1364 hand scribed to the base and has the acid etched Riihimaen Lasi Oy Finland logo with the lynx. Circa 1970s vintage.
It is a rich dark golden amber colour, straight-sided and tapering in - cone shaped. It is handmade/mouth blown glass with a thick heavy base where it is cased in clear. Flat polished rim. A good sized 22cm tall x 8cm base x 4.7cm rim. 
Very good condition for the age. Being handmade it has some tiny internal bubbles, some are stretched and near the rim. There's the tiniest invisible inner rim imperfection and some tiny marks towards the baseline.
