This postcard was issued by the Ghanaian government in Accra in 1958 “Commemorating Prime Minister Kwame Nkrumah’s Visit to U.S.A. and Canada”.  There’s a Gold Coast stamp, with Ghana Independence overprint; and clear postmark.  No address, so the card was not mailed.  A small flying insect got pressed into the bottom reverse–adds character.  Grade: 3
