Welcome to the forum , stephen .
Many of Klimts' works were duplicated/copied , so buying 'Klimt' pieces is a slippery slope .
Klimt first designed furniture for a Greek (Nikolas Dumba) man's music room in Vienna , in 1898 .
A pretty good primer for Klimt is at : abcgallery.com/K/klimt/klimtbio.html .... also some things at klimt.com .
I think you can find some info about the Nikolas Dumba commission at the 'abc' site ...don't quote me on that though ....
