chicago. she's a curator with the holocaust museum. susie, thanks for being with us. first off, why is it so important to launch this project now? >> i think 20 years after we've opened, we are looking at a diminishing survivor community, and this is the last chance we might have to speak with survivors of the holocaust. so the artifacts that we collect on the road these past six months are really the last groups of materials we will get from survivors. from that point on, we depend on the next generation. when we have no survivors, these artifacts are the things that will speak to us. >> and let's talk about some of these items, suusie. most of them have never been seen by the public before and have been made available exclusive to cnn. let's talk about the uniforms we have here. take a look. what can you tell us about the uniforms? >> the uniforms were worn by a father and son originally from germany.
