Does anyone have any information on the photo below? Robert Neff, who owns the photo, published it in a March 3, 2019 Korea Times article entitled "Timber poaching on Ulleong Island." Mr. Neff has said that on the back of the photo is written "Matsushima 1906."
Does anyone know who the people in the photo are? Did Westerners visit Ulleungdo in 1906?
