Kelvingrove Art Galleries

The hanging heads were put there I think in 2000 to bring in the new millenium.
I would welcome some info on this from some of you arty blippers as I may be wrong.
I will need to go back every week as it was one of those days when you get a months worth of blips but can only put one on.
But thats the beauty of this community

Scottish artist Sophie Cave did the heads
