This 1874-1880, 5-Centavos, Peruvian issue was overprinted for use during the early-mid 1880s. It was cancelled at the British Post Office in Callao(a pretty superb, bar numeral(C38) cancel!), Peru! It has a few, shorter perfs, but is otherwise in good condition. Noted imperfections aside, this stamp remains a nifty piece of British and Peruvian philately.
