In my...

...100year old autograph book, a drawing of Charlie Chaplin.

A little bit of info on Charlie Chaplin

Update :
Just researched the Charlie Chaplin signature...I hadn’t thought there was a possibility this was Charlie Chaplin’s signature.

In later signatures of Charlie Chaplin the ‘p’ is different, has a sort of loop.

However, earlier signatures around 1920, about the age of this autograph book, i found a few signatures that were almost identical to this one with no ‘loop’ on the ‘p’.

I wonder....
