Alvar aalto, birch stool, model x600, by artek, circa 1960s. A naturally colored alvar aalto' s x600 stool. It is one of the most iconic models of the famous finnish architect and designer, which is characterized by the singular shape of the fan-shaped legs. It is a refined but at the same time spectacular object, capable of adapting very well both in a domestic context and in an office. This piece is attributed to the mentioned designer/maker. It has no attribution mark and no official proof of authenticity, however it is well documented in design history. I take full responsibility for any authenticity issues arising from misattribution
