The Kinshasa mask was an African mask a Kinshasa shaman gave to Indiana Jones, who kept it on a shelf in his Barnett College office by 1938.
Behind the scenes[]
The mask is a reference to the older LucasArts game Zak McKracken and the Alien Mindbenders in which the player visits Kinshasa to see shaman Nomon Slicinmon who wears an elaborate mask. The shaman will teach the characters how to use a Mayan crystal shard with a crayon map.
