Is there any specific reason behind the different styles of banksy's signature? For example the first 2 signatures as opposed to the bottom signature. Does one sig indicate something the other doesnt or just general tiredness from signing.
It may mean something to him or the person he signed it for. There are quite a few different prints out there with different sybols. I remember a QV with the Ban the Bomb sign on it. I think it was signed but not numbered.
