4 "high back" oak chairs

What a beautiful set of dining chairs. These chairs are from the 1960s from france. Sadly we don't know the origin of them but this is clearly a piece of craftsmanship. They are from a good quality but from an unknown designer. The chairs have a beautiful oak high back and a leather seat. with just enough patina.
