A display board attachment used by machinists in machine shops includes a display board pivotally mounted by posts on a tool box. The display board is pivoted between an upwardly inclined operative position and a horizontal collapsed position. The tool box cover may be readily opened and closed when the display board is in the collapsed position. When the display board is in the operative position, it will support and display a blueprint or shop drawing for ready reference by a machinist.
