Onassis with Churchill sitting inside Onassis's yacht swimming pool which converted into a dance floor. This is a picture that inspired one of the best Mosaicology posts written back in 2010 called The land of the Minotaur and Onassis's swimming pool/dance floor.
This image is quite rare. I have tried to find more regarding this but with little luck.
Please help me continue sharing the passion for mosaic(ology)
