Kolomon Moser Armchair
The above armchair was designed in 1903 by Kolomon Moser for a young couple, Eisler vo Terramare, for the Breakfast Room. Thuja, Satinwood veneer and metal feet.
I took the photo at the Leopold Museum in Vienna in 2012.
When I published this post with the photo below I found out that it was a double of a prior post.
Was sold by Los Angeles Based Szalon which I found via 1stdibs.
