I have a fellow CAF team member that has several items signed by a well known aviation figure from the 1920s/1930s.
Im curious how one might go about determining whether the signatures are authentic.
Never been an issue with this sort of thing w my Robert Taylor prints...so wanted to get some steer in this area.
What is their reason for wanting a certificate of authenticity? Is it for resale/insurance valuation or to prove if the signatures are authentic? If that person desires a certificate of authenticity, please realize that most of them are not worth the paper they are written on. Virtually every single "certificate of authenticity" you see on Ebay is completely worthless. Even the most famous authentication service of them all - PSA/DNA - has a very checkered past, with many stories of deception, embellishment, corruption, and authenticating known fakes. I don't recommend PSA/DNA services for lots of reasons, not the least of which is that they place permanent, possibly destructive chemicals on your signature to "mark them".
To truly authenticate something, they are probably going to have to go to a forensics signature authentication service. These are specialized people that have very specific criminal forensics training to assess authenticity of signatures. These people have training/backgrounds that allow them to testify in a court of law and often times work with law enforcement/FBI. Hiring one of these people is not cheap and the service often will exceed the valuation of the signature. There are several of these forensics experts who have appeared on television shows such as "Pawn Stars" and "True Crime" news shows. A quick google search will provide names of people who provide that service near your location.
Unless you have a very rare, expensive autograph, I wouldn't even bother, to be honest. Just my opinion.
