Re the museum and its long-delayed opening: I would write or call them anyhow, and ask if (1) they are instituting a print sale program in connection with the renovation; and (2) if they have this work out on loan. Storage on those things (especially big paintings) is outrageously expensive, has to be climate controlled, etc. Most curators faced with a long down-time like this will have placed everything they can with other museums. SOMEbody will be willing to talk to you and explain what's going on.
As far as the print sales program, I contacted the Tate Gallery several years ago looking for prints of some of their works (I'm a big fan of British painting and they have a very nice collection). May have just been a coincidence, but after I started bugging them they instituted a very well-organized and comprehensive print order program. You can obtain all major and many minor holdings on archive-quality paper in different sizes. Of course, you won't get that lovely texture on the moon, but a really nice print would be better than nothing at all!
Unfortunately there is nothing like standing in front of the Real Thing. We went to the Five Rings exhibit when it toured in connection with the '96 Olympics. It was almost overwhelming -- a couple of large Russian seascapes had me looking for a life jacket -- my kids were horrified/ fascinated by Artemisia Gentileschi's "Judith and Holofernes" . . . it is undeniably shocking in larger-than-life and living (or dying) color.
This is the one I use: Panorama 32, version 1.31. You may want to use a more recent version (if one is available), but I find that this one suits me just fine. It's so easy to install. If I can install it and figure it out, then anybody can (I'm not technically inclined, at all).
