Spider-Man celebrates his 60th anniversary alongside the Avengers and Mickey Mouse in two covers exclusively available to attendees of this year's D23 Expo, Disney's biennial fan convention.

Both variant covers are drawn by Humberto Ramos and colored by Edgar Delgado for Amazing Fantasy #1000, a recently released celebration of Spider-Man's storied superhero career since his first appearance in 1962's Amazing Fantasy #15. One of the covers shows Spidey receiving a 60th birthday cake from Mickey Mouse as Black Panther, Captain America, Captain Marvel, and Iron Man all stand in the background, each holding gifts for the web-slinger. The other cover shows Spider-Man returning the birthday favor and giving Mickey, Minnie Mouse, Daisy Duck, Donald Duck, Goofy and Pluto their own cake, celebrating 100 years of Disney ahead of the company's centennial, which is coming in 2023.

D23 attendees can obtain the covers by attending the panel "Marvel Comics: Celebrating 60 Years of the Amazing Spider-Man," which is held on Saturday, Sept. 10, and features Marvel editors Nick Lowe and C.B. Cebulski speaking on Spider-Man's rich history. Amazing Spider-Man writer Zeb Wells and Ramos will also be available to sign the covers at another event later that day.

Amazing Fantasy #1000 features a variety of short stories showcasing Peter Parker's selfless sacrifice and enduring qualities, including a tale that imagines Spider-Man as an elderly 60-year-old reckoning with a near-death experience. Creators contributing to the oversized issue include Neil Gaiman -- who penned a story delving into both his appreciation for Spider-Man and his admiration for Spidey co-creator Steve Ditko -- as well as longtime Marvel creators like Dan Slott, Klaus Janson and Jim Cheung.

A Brief History Of Disney And Marvel

Walt Disney and his brother Roy founded the Disney Brothers Studio on Oct. 16, 1923, and Mickey Mouse would become a sensation in 1928 in the short film Steamboat Willie. These humble beginnings would lead to immense growth over the next century, with Disney Brothers Studio eventually evolving into the mass media conglomerate now known as The Walt Disney Company.

The company that would eventually become known as Marvel was founded 16 years later, in 1939, under the name Timely Comics. Marvel became a Disney subsidiary in 2009 in a deal worth approximately $4 billion, ending a long period throughout the '90s when Marvel struggled with bankruptcy. Thanks to the movies of the Marvel Cinematic Universe, Marvel is now a pivotal unit under the Disney umbrella, right alongside Star Wars and Pixar.
