This is off topic but I thought someone on this board might be able to help.
I purchased a lot of silent film star photos some time ago. Most are autographed. I am almost certain the signatures are authentic. The photos are definitely from the period and many were made out to the same woman. She must have had some sort of in in Hollywood.
These are two of the better signatures in the group - Harold Lloyd and William Hart. I am hoping someone here can confirm that these signatures are authentic and can provide me with a value. Thanks!
