This is an antique original 1919 linen blueprint.  The blueprint shows the plans for the railway dry dock cradle built at Astoria Marine Iron Works in Oregon in 1919.  The plan measures 41 1/2″ x 30 1/4″ and is in very good condition for its age.  There are brown foxing spots and darkening of the edges, which add to the steampunk appeal of the piece.
I will be listing several additional antique marine related blueprints, so please take the time to view my other auctions.
