Lot no. 6203

"87" Postage due charge mark, used by mistake on a partly prepaid single rate folded letter with contents sent from Barcelona May 6th via Paris to Stockholm. The postmaster noticed his mistake crossed out the 87 mark and added the correct "72". Transit cancels on reverse: "ESPANA LA JUNQUERA 7 MAY 62", "PARIS A QUIEVRAIN XY MAI 62" and "HAMBURG K.S.P.A (D.) 12/5. 1862". Slight archival fold across the charge marks.
