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. 
Good condition with no obvious scratches. Base shows signs of its age. There's the tiniest inner rim imperfection, see photo 6-7.
