Abstract: A portable drawing board device adapted for helping art students to draw perspective drawings, includes: (a) a generally rectangular-shaped, flat drawing surface on an upper surface of the drawing board, the drawing surface being adapted for supporting a flat drawing substrate; (b) a pair of parallel side grooves in an upper surface of the drawing board, each being parallel and adjacent to one of two opposite sides of the drawing surface, and extending the length of the drawing surface; (c) a pair of first slide adjusters adapted for sliding up and down along the side grooves; and (d) a pair of movable pivot arms, each movably attached at one end to a slide adjuster; wherein, when the first slide adjuster is in the side groove, the pivot arm extends over a portion of the drawing surface, and is adapted for assisting a user in drawing horizontal and diagonal lines on the drawing substrate.
