This is a rare issue of The Mighty Thor, published by Marvel Comics in May 1987. The story features a cast of characters including Thor, Lady Sif, Loki, and various other Asgardians, as well as some unexpected guest appearances from X-Factor The Beast and Iceman. The artwork is beautifully rendered by writer/artist team Walter Simonson, Sal Buscema, and Evelyn Stein.

The comic is in the tradition of US Comics and falls into the Copper Age (1984-1991) era. The cover art, also by Walter Simonson, is a dazzling image of Thor in battle with the Midgard Serpent, who is also disguised as Fin Fang Foom. This issue, number 379, is a must-have for any serious collector of superheroes and fantasy comics.
