PERU - CHINCHA/GUANAPE ISLANDS - 1d BLUE ON COVER BY THE PSNC STEAMER 'LIMA' TO VALPARAISO; 3 Apr. 1861 EL (minor creasing; in French) ex "Iles de Chinchas" to Valparaiso endorsed "Par Packet Anglais" (the S.S. 'Lima' in this case) with 3m 1d Blue tied (also by indentation) by partly fine dotted oval "ISLAS[?]" mark, but having no other postal markings. Plus 22 Sept. 1869 E with fair 1d Green tied by oval-framed "Y. GUANAPE" cancel, presumably of the Yslas Guanape. Rare origins for early letters; these islands were all used for the production of guano. (2 covers) Cross Reference: PERU
