1918 Cover to England with fine type I "TRISTAN / DA / CUNHA" cachet partly covered by British "Opened By Censor 3677" seal, carried by ship to Rio de Janeiro where a Brazil 200r stamp was applied and cancelled (Apr. 29). Small surface fault at lower left corner, otherwise fine and a remarkable WW1 period censored cover (just one other type I censored cover recorded from Tristan in WW1), unique with a Brazil stamp added in transit.

1929 Canadian Pacific envelope to USA with G.B KGV 2½d cancelled by red "TRISTAN DA CUNHA" type IV cachet in red, a partial London Paquebot machine in the upper left corner. Carried by the "Duchess of Athol" which called at Tristan on February 24th. A fine example of the uncommon type IV cachet. Photo on Page 238. (Image1)
