A ton of history is collected in this tasteful and powerful exhibit. Done with a poet's or artist's sensitivity, readily accessible, yet scholarly in the best possible way. Not "heavy", even more moving (for me) than the Holocaust museums, which are very moving in a different way. Wonderful cross-section of ages in attendance. This is an exhibit you will never forget. I found it helpful to go alone, so that I could focus on the material more fully. And remarkably, the only venue on the East Coast. Supposedly, there are no plans for New York or Washington, so we in Boston are lucky. One tip: There is an enormous amount of material. Do not skim or rush - Just take your time, go through it on your own rhythm, and plan to return to take in more.
