Grebo masks belong to the Kru cultural group. They represent the spiritual forces of the unseen world living in the forest, in a similar way to Bete masks, even though they differ in style and size. Grebo masks are very rare and they can reach up to 1 metre.
These masks are shrouded in mystery. They are characterised by an elongated nose and multiple pairs of tubular eyes. It seems they have strongly inspired Picasso at the beginning of the 20th century.
