Since this shows the facility in the process of being built, I think one could safely date this picture to around 1915. This plant went on line in 1916 and was acquired by Mead in 1920.
I have a couple of these blue-tint cards. Surprisingly, there is absolutely no photo or publisher credit anywhere on them. These are divided back, white border cards which were in vogue between 1915 and 1929.
