I found this map of Map of Colonial Africa in 1913 (Wikipedia: Colonial Africa 1913 map). Amongst the big players it shows the Spanish possessions in the Rif War and Sahara and the Portuguese possessions in Angola and Mozabique. It also shows how the Portuguese coast-to-coast aspirations embodied in the ‘Pink Map‘ conflicted with the British “Cape to Cairo Red Line”.
