Robby The Robot by Ramon Perez.

At this year's Thought Bubble comic convention in Leeds, I came across Ramon Perez sat at a table busy working on a commission. I didn't recognize him and he didn't have his name visible anywhere. So I asked him who he was and what he'd worked on.
'Ramon Perez', he politely responded, 'I'm currently working on the X-Men and Wolverine but I also illustrated A Tale Of Sand'.
I actually have a copy of A Tale of Sand, it's based on a film script by Jim Henson that never saw a camera's lens. I remembered being struck by how fluid the artwork on that book was and so promptly asked him for a robot commission.
He asked what robot I wanted, and I said that I'd happily leave that up to him.
He suggested I come back tomorrow.
Which I did, and was pleased to collect the image of Robby the Robot, from the classic 1956 movie Forbidden Planet.

Very nice indeed.
When I collected this I took the opportunity to get Ramon to sign my copy of A Tale Of Sand, of course.
