RESUMO
A puzzling raised-line drawing of a head by a blind man with no experience in freehand drawing has eyes placed outside the boundary line of the head, not inside. After scribbling, in the John Willats theory of drawing development, 2D "regions" on the page stand for 3D "volumes" in the scene. If Willats is correct, in very early drawing development circles touching the boundary line from outside may show the eyes are "embedded," and very early drawing development may be similar in the blind and sighted.

An unusual drawing of a road has two lines converging sideways, from right to left. The left side of the picture is explicitly described as the location of the observer. Also, the fronts of the cars on the road face left, with the largest car on the right. This sideways perspective is novel. In linear perspective, roads running parallel with the picture surface should be drawn with parallel lines. Lines for roads running orthogonal to the picture surface should converge with elevation. The rule for roads is if converging, then upward, and if sideways, then not converging. The sketch is by a blind woman with modest experience in drawing, including perspective. It suggests an intermediate stage of drawing development, with inconsistent use of the observer's vantage point, in keeping with theories of perspective drawing by the blind and sighted of Willats, Kennedy and others.
