ABSTRACT A drawing board suitable for use in preparing perspective drawings is provided with a pair of arcuate guide surfaces facing towards one another and situated towards one side of the drawing board, with a recess or depression between the arcuate guide surfaces, so that a drawing instrument having projections capable of engaging the arcuate guide surfaces, can be readily moved from one arcuate guide surface to the other to enable the drawing instrument to point towards vanishing points on either side of the drawing board. The drawing board may have straight guide edges, as well as additional arcuate guide edges, one of which may be directed towards a central vanishing point. The multi-purpose board can be used to produce various types of perspective drawings and seven vanishing points are shown.
