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.

Kryten by Robert Llewellyn.

I met Robert Llewellyn last weekend at the Thought Bubble comic convention in Leeds. His main reason for being there was to promote his books, yep, he's a science fiction writer when he's not on TV. He came across as a genuinely nice bloke, and I picked up a copy of the first in his trilogy of books,

It sounded an interesting concept where his trilogy explored the idea of what would happen if something significant in the world we know was the complete opposite.
Free with every copy of his book, but not the reason I bought it honest, was a signed photo of him as Kryten.

Still one of my favourite Sci-Fi characters.
(Note - you should check out Robert's blog... very interesting stuff).
