Draw a stencil shape of four children with different features on a staircase

Draw a stencil shape of four children with different features on a staircase, where two are standing, two sitting, all wearing a shirt covering their face and pointing books as if they were weapons, looking like bandits from the favelas of Rio de Janeiro. The books should be of different sizes and the children should hold them as if they were holding a pistol., a rifle and machine guns, but instead of weapons, put books.
