Lot of 100 personal checks signed by legendary screen siren ''Mary Astor'' and made out in her hand. About half of the checks are dated 1968-1970 and are printed with her addresses in Mexico, and Laguna Hills and Fountain Valley, California. The other half are from 1980, the year she starred in ''Hollywood: A Celebration of the American Silent Film,'' a documentary in which she discusses her early career. Measuring 6'' x 2.75'', checks bear standard cancellations and are in very good condition.
