Michelangelo.A youth beckoning; a right leg.c1504-1505.recto.pen&ink&chalk.[Brit.Mus.London]

This is commonly acknowledged to have been a free interpretation by Michelangelo of the Apollo Belvedere. The faint vertical line of reighting to the left of the nude sketch's head reads: "I once was nude, but now am badly clothed." Might it be Michelangelo's own comment on some aspect of his draughtsmanship in this case?
