Two Nude Male Figures

This is a really nice drawing to do a master copy of, using charcoal, white chalk, and blending stump. It's nice because one can see exactly where the artist used the stump to carve out the shadow shapes on both figures. Note how the artist sticks with the rule of not, or rarely, letting any of the white chalk blend into the black charcoal, and he keeps some area of open paper tone between the white and black. 

Another reason this is a great drawing to copy is it involves two figures and both are foreshortened. Foreshortening of figures and limbs is a tricky thing to make look realistic, so this drawing offers the change to study and practice multiple areas of foreshortening.
