Wonderful Monday Night with Mr. Rick (hosted by Ben Green).
Oh buddy - when asked at the show's conclusion which piece of European art Rick would most like to own, he replied
"The Kiss" by Gustav Klimt.
OK - some are so large to make ownership impossible ("Coronation of Napoleon and Queen Josephine", "Liberty Leading the People", "Raft of the Medusa", "Las Meninas" etc ) - and some are painted on walls ("Last Supper"), etc - and, of course - large sculpture presents a problem - although "Venus of Willendorf" fits into a shirt pocked - but - are you kidding - "The Kiss"?
My vote - "Garden of Earthly Delights" - a Bosch triptych that was made to be portable. Right into my living room.
(Thanks for the daydream,)
What's your pick?
