Wim Den Boon (1912-1968) was a Dutch designer, interior designer and architect. Den Boon was a strict thinking man who believed strongly in the transforming capacities of architecture and design who left behind a small body of work. Most of his furniture was made for specific projects. This particular chair is a fine example of Den Boon's work and dates from the early 1960s . The last photo shows the chair in its original setting. It has new leather upholstery. The new leather is an exact copy of the original upholstery as can be seen in the last photo. I have official proof of authenticity such as vintage catalogs, designer records, or other literature sources and take full responsibility for any authenticity issues arising from misattribution
