This is an original panoramic photograph taken 1918 of the Vancouver Barracks Washington State U.S. Army Spruce Production Division cut-up plant, taken by Eugene Ralph De Monbrun (De Monbrum) – a U.S. WWI photographer and draft registrant. Eugene Ralph De Monbrun (also documented as De Monbrum) was an Oregon-based photographer active around 1900-1919, was registered for the U.S. Civilian Draft in 1917-1918 for World War I, he resided in McMinnville, Oregon. The photograph is marked in the negative, “Largest Aerial Cut-Up Plant in the World” and signed “Photo by De Monbrun”. Ground was broken on December 14, 1917 on the Vancouver Barracks Washington State, massive United States Army Spruce Production Division on their cut-up plant and was built by soldiers in just 45 working days. It was built on the polo grounds at Vancouver Barracks, across the river from the division’s headquarters in Portland, Oregon. They processed twisted Sitka Spruce logs into straight-grained, aircraft-grade lumber for Allied warplanes during World War I, the facility ran 24-hours a day on three eight-hour shifts, ultimately producing 150 million of board feet of specialized lumber before operations ceased with the armistice in November 1918. The image shows a sepia toned black and white original photograph showing the sprawling production site with hundreds of canvas U.S. Army Air servicemen tents and various soldiers seen throughout. Very few images of this size from the production site have been offered on the public market. This is shrink wrapped to matte board and shows some edge wear and some cracking on the ends. The photo measures 7 7/8" L x 48 3/4" W.
