Why, that doesn't make any sense at all.
If I had $51mil, I'd spend 50 of it on that painting.
Figure a few more $million on special storage and security for it over its lifetime in your collection...
Or you can spend a few $thousand on high def large screen TV set / monitor and high quality digitized reproduction of this and/or your other favourite paintings and have them displayed any time you want. It’s good enough for Bill Gates (of M$).
