Well, for one I like images – perhaps they remind of a place where I have been. Or I like the artwork. Or the postcard reminds me of someone I used to know or a place I liked to visit. Take for example the West coast of Africa. I lived in Ghana for a year 1988-1989. So all postcards relating to Ghana and more widely the West coast of Africa are of interest. I am currently reading Mary Kingsley’s book Travels in West Africa. And I have become friends with a person from Upper Volta-Bourkina Faso. History, literature, art, politics, geography -it can all be there in a humble postcard.
