Academy Award-winning actress Mary Astor autograph letter signed. To her agent Gloria Safier, letter discusses various edits pertaining to her upcoming book, ''A Place Called Saturday''. Reads in part: ''Dear Gloria -- I need more copies of 'Saturday.' I've cut my list down to fourteen (more) -- which are musts...I will be leaving SW December 15th at the outside. I've sold this place and that is the buyer's occupancy date. I couldn't be happier...'' Signed ''Mary'', letter on two pages measures 8'' x 6'' with a vertical fold and minor toning. Very good.
