Mahogany Corner Chair (model Opus 587) designed by Jac van den Bosch for 't Binnenhuis in Amsterdam, Netherlands 1910s. This amazing chair is simple and stately yet elegant and a bright addition to any interior with its purple fabric. Pure craftsmanship with nice patina and in very good condition.
This chair has been very well described in literature, including pictures. You can find it on page 235 of the book: "Rechte stoelen, rechtschapen burgers: Wonen volgens 't Binnenhuis"
