Abstract: A portable writing and reading table assembly includes a pair of spaced-apart stands, each of which includes a generally flat base, an upstanding post secured to the base, and a generally flat writing board, having an elongated holding bar mounted across the lower end thereof and extending outwardly from the front face thereof. Means are provided for rotatably mounting the board between the posts of the stands to permit rotational movement of the board about an axis perpendicular to the longitudinal axes of the posts. Means are also provided for locking the writing board at a desired angle of inclination relative to the axes of the posts.
