Several interesting requests come in each month. Many requests are about passport copies from relatives. Note: Passport offices do not keep copies of a passport itself, what someone can get in the best case is a copy of a passport application, with or without a passport photo.
I can support you in identifying an old passport, stamps, and visas, signatures, handwriting, and collectible value. Eventually, I will ask you for pictures of your document(s) at a later stage to do a better evaluation. This site is about passport history!
I do not any genealogical research or citizenship consulting!
Take a look at my link list, which might be useful for you. Usually, I aim to answer your request within 48 hours.
