A super Rosenthal, West Germany, white porcelain 'UFO' vase by Werner Uhl. It's likely a 1960s/ 1970s design; the base stamp dates this one to 1981. Mid-century modernist and minimalist in style, with a bit of Space Age and Bauhaus influence.
Model number 3537/10 - 3537 being the model number and 10 being the height. A simple rounded squat shape, bulging out with hoops to the centre. The design is very hard to find and is known as a UFO. It's bright white and glossy glazed in and out.  
A smaller sized version of the design: 9.5cm tall x 12cm widest. Stamped on the base with the Rosenthal logo, and indented with the model number 3537/10.
Excellent condition. Super stylish and cool.
