Candle Holder Signed Kosta 67981 Warff

I recently purchased this votive holder at our local thrift shop. Could someone help me with
identification and an idea of when it was made. It is signed "Kosta 67981 Warff". Thanks
in advance.

Hi, it's by Kosta Boda glassworks (Sweden) and is a design either by Goran or Ann Warff, the 67981 will be the design/pattern no. If you Google 'Warff Kosta' you'll find pages and pages of info, unless anyone knows instantly what particular design that is, it's a matter of trawling through the links.

In fact, if you google what's on the base of your votive 'Kosta 67981 Warff' there are a few auction listings that suggest it's a Goran Warff design and gives other info.

Google is your bestmate in glass researching and should be your first port of call.
