Fan mail / signature collecting is another hobby of mine.
I've never sent out anything that would kill me if I didn't get it back.
Usually I just print a nice high res photo and send it to them in a SASE. This time I sent a poster.
And their have been people I've never heard back from ever, a few Return to Senders, and then sometimes it works out.
But you'll never know if for certain if a sig is 100% real unless you watch them sign themselves, that I agree with.
But at the end of the day you just gotta have faith I guess.
And I'm just doing it cause I enjoy it.
A lot of people say it ruins an otherwise perfect poster and other people say why bother at all if you'll never know it's real or not.
Guess I could have every one of my items JSA, PSA, ect authenticated, but even then, sometimes sigs that are real are "proven" to be fake and visa versa.
But like I said, a little faith, and research on the person you're sending to and comparison of sigs to known real ones and you get an idea.
That and again, at the end of the day, it's all just fun and exciting for me as a hobby.
