I think the signatures top to bottom are-

Ricky Ponting

Peter Siddle

Brad Haddin

Michael Hussey

Simon Katich

Phil Hughes

Mitchell Johnson

Ben Hilfenhaus.

Looks to be signed in ink and all appear to be genuine hand signed, I have no provenance, or COA, so please do not bid if you have any doubts.

The bat is a Kookaburra Kahuna Doom, grip is perished as you can see and a stain to toe.

Looks good to me, please study images to make up your own minds, again if you have any doubts please do not bid, I’m giving no guarantees as to authenticity of signatures.
