Unusual large onoto pen advertising figure shaped post box

A lovely large unusual advertising figure for onoto pens. Cleverly figured as a large pillar post box. With the connection to pens and sending letters. Made from cardboard it's a lovely large display piece possibly from a stationers shop window. With the onoto pen wording being 3D modelled it's a great advertising piece.
