Fantastic Four #186 (1977)

"Enter: Salem's Seven!" Written by Len Wein. Art/cover art by George Perez & Joe Sinnott.  The Fantastic Four faces three daunting tasks! First, stop the planned execution of Agatha Harkness; second, find and rescue Franklin; and third, defeat a new group of super villains...the Salem Seven! How will the FF match up against Brutacus, Gazelle, Hydron, Reptilla, Thornn, Vakume, and Vertigo? Hopefully, it's favorable, otherwise everything will be lost!

Key book; first team appearance of the Salem’s Seven.  Very good+ condition.
