1864: Line Engraved 1 penny red, plate 124, lettered GH, good colour and perforations mostly fine, tied by two strikes of a duplex “HOLLOWAY AU 13 75” to a small envelope sent to Paris, with framed “INSUFFICIENTLY PREPAID”, handstruck “5”, an inspector's cork handstamp cancelling the red oval “PD” and a transit cds “ANGL CALAIS 14 AOUT 75”. Reverse, arrival cds “PARIS 15 AOUT 75”. One or two perforations affected by edge, although remains appealing. An interesting and rare cover from the French Interim period between 1 July 1875 (begin of UPU period) and 1 January 1876 (begin of France's membership).The postage due marking “5” was a pre-GPU calculation.
