Hey there, I love to collect signatures, or famous people's signatures!
That is interesting whos signatures do you have
I have some from previous presidents like Barack Obama, athletes (many football) and movie stars!
Wow that is really neat.  I don't have anything cool like that
It's a really fun hobby called philography. I highly recommend starting if you're looking for something to do.
Interesting I didn't know that collecting signatures had a special name.  
Indeed. Some collectors even seek particular types of autographs. Some try to stay with Nobel Prize winners or even American heroes. I know someone who set out to find military leaders from World War I. Mine is a bit more generic, though I do love to organize mine into categories.
it sounds like it can be a serious hobby about like stamp collecting for some
Definitely. Just like stamp collecting, there can be a long history and a way to keep track of time passed. The oldest autograph is actually a Sumerian clay table rom about 3100 BC. It has the name of the scribe Gar.Ama. It's fascinating!
