A very small piece of art glass or ash tray in clear glass and black by Kaj Franck KF 211. As the idea was that also utility glass should be designed and beautiful, this is, believe it or not designed to be an ash tray!
On the last picture you see this piece together with its cousin KF 210, a designed bowl in dark red color. This bowl is for sale elsewhere on this site.
This Chestnut has got a couple of very minimal nags.
Size: 65mm x 60mm x height 25mm
Condition: Good with very minor wear
Signature: K. Franck Nuutajärvi Notsjö -57
