I think this card is from the 1970s because on the back Sri Lanka has Ceylon in brackets after it. Sri Lanka changed its name from Ceylon in 1972. This card is from a PhD student from Tezpur. The card is of the Botanical Gardens found in Peradeniya, Kandy, Sri Lanka.  Tezpur is located in norther India on the banks of the Brahmaputra River. There are about 102 000 people who live here.
