Artek Model K65 bar stools designed by Alvar Aalto. The bar stool version from the most famous design by Alvar Aalto. It's from the mid 60s or earlier. This can be seen from the by the wooden finger joint in the seat. Artek only used this joint up until the mid 1960s, later models don't have the finger any longer. It's made in Finland from solid birch wood L-legs. It's in great vintage condition.

Alvar Aalto, together with carpenter Otto Korhonen, began experimenting with bending solid wood in the late 1920s. The collaboration resulted in an L-leg, which was an invention that took a step towards the mass production of Aalto’s furniture. Alvar Aalto patented the L-leg bending technique in 1933. L-leg became to be the standard component for Aalto’s furniture design and based on the invention also Y-leg and X-leg were later developed.
