So she got the painting - not that she wanted it, but she did want recognition that it was rightfully herswhich the Austrian Government wouldn't do, hence the big court case. With the painting now hers, the Austrian government and their National gallery, which I think is at the Belvedere in Vienna, wanted to buy it back from her. This was so it could remain in Austria along with other works by Klimt, including ''The Kiss', on display in the Belvedere.  Not surprisingly she told them to get 'stuffed', and it was sold to a private gallery in the USA, in New York  I think.
