1874: Congress of Berne Special rate to and from Cuba and UK. Two covers, mounted on an exhibition page, informatively presented, illustrating the elusive Special rate to non-member Cuba, made possible by GPU transit. Comprising an 1876, unpaid stampless lettersheet from Havana to Edinburgh (Scotland), bearing a manuscript “10” in blue, and the handstamps “T” and “6d” in circle in black. Reverse, New York cds and a railway transit cds “CARLISLE SORTING TENDER EDINr. DE 11 76”. Some soiling and creasing. Second example; 1864, 1 penny red and 1876, 2½ pence rosy mauve, plate 7, tied to an entire from London to Havana, with handstruck “4” in black and manuscript “10” in red, sent via New York at the 3½ pence rate. Minor imperfection. Scarce duo.
