Summary
A steel plate with extensive surface oxidisation on the reverse. The obverse has bevelled edges and has a wax treated surface which has avoided the worst of the oxidisation, and there a piece of white tissue paper stuck to the surface, with the edges are folded over to the reverse. The entire plate and tissue paper are wrapped with brown paper, which has been stained by the oxidisation of the underside.
