FWIW and just an idea for any of you who have fathers or grandfathers who are veterans of past wars.
My father was a P-51 pilot during WW2. When my sisters and I were cleaning out 63 year accumulation of possessions from their house after my father passed away, I came across his old foot locker. Some of the items in it - his flight jacket, helmet and goggles, some maps and other such things were donated to a small local museum.
But the prize was a couple of bundles of letters he had written home from England and Belgium, and later Germany. My mother got all the letters to her, and spent the rest of her years reading and re-reading them, and putting together her own journal or scrapbook. I've taken the letters he wrote to his parents, brothers and sisters, his personal diary, and his log book, along with about a thousand B&W photographs and am turning them into an e-document to be put on CD or other electronic media and shared with both of my sisters and our kids. It's a bigger job than I thought it would be, getting everything in just the right place and matching up log book, diary, and letters by date. It will be well worth it when it's done.
