Hey everyone!

This is a piece of paper where on one side you have Mick Jagger, Keith Richards and Bill Wyman's signatures. These have been certified by Tracks to be genuine.

On the other side (shared below) you have a signature by Brian Jones, which I don't think has been looked at by Tracks, and another mysterious scribble (I don't even know which side is up).

Any views on the Brian Jones autograph, and in particular on who the mysterious scribble might be?
