The first appearance of the famed Wolverine of X-Men was in The Incredible Hulk issue 180. That artwork was long deemed lost; however, a recent discovery uncovered that the artwork wasn't lost after all! 

According to the San Francisco Gate, the recently-found artwork will now go up for auction in May, in order to benefit the Hero's Initiative, which is a non-profit group dedicated to help comic book writers who are in times of trouble. 

The artwork, drawn by Herb Trimpe, was deemed lost back in 1983... until the person it was given to contacted Heritage House about selling it to them. 

"I went out and met with the owner and it wasn't until I was there and actually saw it that I fully believed it. It's a pretty amazing thing," said Todd Hignite, Heritage's vice president.

Furthermore, according to US News and World Report, the owner -- who asked not to be identified -- was given the ink, graphite, and blue pencil drawing as a gift from Trimpe.

Wolverine is a fictional character, a superhero that appears in comic books published by Marvel Comics. Born James Howlett and commonly known as Logan, Wolverine is a mutant who possesses animal-keen senses, enhanced physical capabilities, and a healing factor that allows him to recover from virtually any wound, disease, or toxin at an accelerated rate. The healing factor also slows down his aging process, enabling him to live beyond a normal human lifespan. His powerful healing factor enabled him to survive having the near-indestructible metal alloy adamantium bonded to his skeleton. He is most often depicted as a member of the X-Men, Alpha Flight, or later the Avengers. 

The character first appeared in the last panel of The Incredible Hulk #180, with his first full appearance in #181 (cover-dated Nov. 1974). He was created by writer Len Wein and Marvel art director John Romita, Sr., who designed the character, and was first drawn for publication by Herb Trimpe. Wolverine then joined a revamped version of the superhero team the X-Men, where eventually writer Chris Claremont and artist-writer John Byrne would play significant roles in the character's development. Artist Frank Miller collaborated with Claremont and helped to revise the character with a four-part eponymous limited series from September to December 1982 in which Wolverine's catchphrase, "I'm the best there is at what I do, but what I do best isn't very nice," debuted.
