Any ideas what this artwork is? It's inspired a famous song, and it is now owned by David Gilmour of Pink Floyd fame.
In that case, l shall enlighten you.
It's non other than Julian Lennon's childhood work, 'Lucy in the Sky with Diamonds'. He told John Lennon that it was the name of the artwork, and John duly nicked the title for the song of the same name.
The Lucy who is in the sky, was Lucy O'Donnell, a class mate of Julian's who later became Lucy Vodden, and who died in 2009, but as to how David Gilmour came to own it, l have no idea (and can't be bothered trying to look it up).
