This event seemed worthy of some background, so we borrowed this from Wikipedia:  “The Tan-Tan Moussem is an annual gathering of more than thirty tribes from southern Morocco and other parts of Northwest Africa in Tan-Tan, a town in south-western Morocco. In traditional Berber culture, a moussem is ‘a type of annual fair with economic, cultural and social functions’.  This particular gathering was first held in 1963 to ‘promote local traditions and provide a place for exchange, meeting and celebration’. It is said to have been associated with Mohamed Laghdaf, a Saharan leader who fought the French and Spanish colonizers for decades, died in 1960, and was buried near Tan-Tan. The gathering was banned by the authorities in 1979 due to security concerns, but was revived again in 2004.  Nomadic tribes travel to the moussem from all over the Sahara, making it the largest gathering of nomadic tribes in northern Africa. Around 800 tents are set up to accommodate them.”  The postcard is unused and almost certainly came before 1979.  Grade: 1
