Board for the educational development of the drawing, characterized because, either directly on its surface or by means of the incorporation of an appropriate sheet, it has more or less complicated representations, on which a transparent sheet of the same dimensions is placed, fixed by means of pins that go through the holes made in their vertices and are housed in the corresponding ones of the board, so that the student traces the original representations on this sheet, educating his hand and mind to the elementary rules of drawing, which may be the board of any nature and, even, have a superior spring-loaded housing for the transparent sheet, with the particularity that said housing has, throughout its mouth, a sponge, pad or similar that, when the sheet is collected, it erases all its content and leaves it ready for a new use.
