Superheroes fan and buyer, Rebecca Armstrong Fleming said:
"Stan Lee has hand-signed these amazing covers, so to be able to own one of these is a once in a life time opportunity."
Six iconic superheroes are starring in the debut 'Marvel Comics' art exhibition at a gallery in Cumbria.
Spider-Man and The Incredible Hulk are part of the collection on display at Treeby and Bolton in Keswick.
Each limited edition piece has been signed by the 90-year-old American comic book legend Stan Lee.
