Gigantic 40x60" full-size model plan for a WWI BE2, blueprint format, British origin. Folded to a 9x11" size, some corner chipping, paper slightly brittle. Needs to be flattened and linen mounted. No date but I'm guessing about 1935. Picture is of logo in upper left corner. Striking imager and would make a wonderful wall decoration. Moderate price; not often found.
