Lion or Monkey Optical Illusion
Self-taught artist Humberto Machado enjoys working with many types of mediums but finds creating ambiguous drawings to be the most fun and the biggest challenge. Using negative space in this drawing, he presents both an angry (hungry?) lion and a cheerful monkey swinging from a tree branch that occupy the same space.
One of my personal favorites from Humberto Machado is called Mad or Sad? and features an ambiguous pair of faces occupying the same space. More of Humberto’s ambiguous drawings can also be found in his latest book from Tate Publishing titled What Do You See?
