[Michlib-l] Expert to verify political signatures

If anyone has any ideas for me that would be great! I have a patron who is looking for an expert to verify signatures and verify that items are originals and not copies on framed photos and correspondence. Patron has purchased many political posters, buttons, records, and letters to Mr. Kettle, the Chariman of the Republican Party, from Livingston Co. These documents are from Nixon and Reagan to Mr. Kettle. My patron would go anywhere in Michigan. Thank you very much for helping if you can! Have a nice day! I am clueless!
