The MOCA rocks, too. Last I was there they had a Rothko hanging next to a haunting Munch, I think borrowed from the Getty. Really cool to just look and compare, the colors, the light, the glow. Did you catch the
Visual Music exhibit last spring, it was in DC earlier? So amazingly Cool! Synethesia baby.
Also, have you been to the Armand Hammer museum at UCLA? Great way to spend a day. The edge of a Universty museum's temp exhibits + an amazing ongoing exhibition of masterpiece after masterpiece.
As for your hunt, If you cant find a print reproduction from the holding archive/museum, you could work with a skilled, historically accurate, passionate calligrapher.
Maybe try here

good hunting.
