The story of this incredible feat is recounted in Bob Greens's book Once Upon a Town: The Miracle of the North Platte Canteen.
In addition to the canteen, the museum had "vignettes" of everything imaginable: kitchen, laundry, department store, music room, funeral parlor, photography studio, a huge salt and pepper shaker collection, hospital, post office, and a sewing room. Most of the items were from the 1940's. I was definitely born too late!

This tattered American flag from WWII was my favorite textile in the museum.
