Prototype of Wolverine, published 1.5 years prior to Wolverine's first appearance
Andy Olsen, a comic fan, created an original character concept of The Wolverine who had regenerative abilities, a metal exoskeleton and was the product of experimentation
There is some question as to whether the Wolverine briefly introduced in Hulk #180 was inspired by this concept though Andy Olsen was never credited or compensated
