I'm not sure which side of this I like better; together they add up to provoke romantic visions of living on a houseboat! On one side is a plan drawing, detailing where the bunks, W.C., couch, dishes, and flour will go, and on the other a profile view and notes on dimensions, materials, etc. and the fact that the roof will catch and feed rain into rain barrels if desired. As Puget Sound is mentioned I'd think its maker was from the Pacific Northwest, and I certainly hope they got their boat built! 

12 x 7 1/2", clearly with old horizontal fold lines and a few small stains, but otherwise very good condition. I received it folded and have placed it under weight to try to flatten in out.
