Auction 333-341 Nigeria, Cameroon, Sudan & Worldwide Postal History - Day 4

1892: Postal Stationery Card, 1½ d. red-brown, surcharged by manuscript red ink to reduce to 1 d. by deleting "HALF", used from Lagos to Hamburg, Germany, dated 26 July 1893, cancelled by "LAGOS / W. AFRICA" single circle in black, with a faint "PAID / LIVERPOOL / BR. PACKET" in red dated 28 July 1893, partially overstruck with arrival "HAMBURG" double circle dated 29 July 1893 in black. A fine and rare card. Cert RPSL (2017) which states "..red ink matches the ink on postally used cards with deletion applied after the obliteration.." and "...is not an official issue."
Note: The author of the definitive reference book on Nigerian postal stationery (published by RPSL in 2023) believes it is entirely feasible that manuscript surcharges were issued.
