“Dining Room of Christian Kold School,” near Odense, Denmark, ca. 1915, an instructional hand-colored lantern slides, via OSU Special Collections & Archives (Oregon State University) Commons on flickr.
I like the repetition of white squares and the somewhat wilted cornflowers (?) across the room. The slide was used during university lectures, possibly about alternative educational methods, including the Danish folk high school movement.
Perhaps the outstanding feature of the Folk High [S]chools is the sociability which is developed. Dining quarters are provided for all students and in the dining room the faculty and students always eat together. . . .
