Thank you for submitting your item for appraisal. It is impossible to identify all the signatures within one appraisal. The booklet # 20 has the signatures of Linda Darnell and Juanita Stark on it. There are some collectors who would collect group signatures, but most collectors go for just one particular actor or actress. Therefore you can´t add up the value of all the signatures on one booklet. Most of the the other signatures on the other booklets are by lesser known actors, e.g. Susan Hayward. And keep in mind that some actors are completely forgotten today. The estimate is for a single booklet.
