Outer 1855 Norwich to Derby with 1d red Star tied by sideways duplex cancel of Norwich 575 dated DE 22 1855. Backstamped by DERBY CDS dated DE 24 55, plus ROCKLAND double rim CDS in bluish ink. Rockland appears to be the sending post office, but has then been forwarded to Norwich to be cancelled. Interesting piece, some of the writing on the outside of the envelope seems to refer to parties in a deceased estate
