Teak Wall-Mounted Valet Adam Hoff & Poul Østergaard  

it depends
i have seen this piece sold at a major auction house of modern furniture here in the u.s.a. for around $350.00, but that does not determine value. it just so happen that there were four crazy people wanting the same exact thing at the same time. stick to what you can afford or willing to spend on and let the crazy people overpay.
it is a very useful piece. mine came from the salvation army for $1. no one knew what it was.

Just bought this wall valet design last week, and it is currently in shipping. Part of the 1964 Cabinetmaker's Guild exhibition.
The nice part about items like this is that they can easily fit on a wall, and I don't have to rearrange the place like I would for a newly acquired chair or side table. The only question is whether I hang it in the bedroom for presumed actual use, or down in the living room as a sculptural piece only.
Attached photos are not of my actual purchase, but rather the same model found online. I believe there were at least three different shades of blue offered, as well as a natural wood backdrop.

The living room wins out. Can't help but think of the Joseph Cornell boxes each time I look at it.
