I hope that one day someone will be able and willing to tell the world a little more about this work. Technically it is amazing what ever size it is. It is carved marble! Aesthetically it would be difficult to better; certainly not a classical pose and not obviously controversial in any way (couldn't offend any real person).
So, Ok what is it that I like about it?
‘A sleepy girl on a hammock’. As you may only look (unless you own one!) what more could you want? Probably top of the list so far.
