The Tower (or Castle as it’s also called) of the High Evolutionary on Wundagore Mountain from the Mighty Thor #135 (Dec’66). Its first appearance here is by Jack Kirby, Vince Colletta, Artie Simek and Stan Lee. This is obviously a reprint and restored version of the original printed version of the issue, but the coloring was kept the same more or less. There’s no escaping Kirby’s awesome asymmetrical design sense when you’re reading Marvel Age Fantastic Four and Thor issues.
It’s not really news, but it still is a wonderful discovery when you see long standing elements of the Marvel Universe show up for the first time, fully formed and recognizable. Obviously, the design of the High Evolutionary’s Tower will change artist to artist, but other elements of this two-part story (starting in Thor #134), such as the High Evolutionary himself, the Knights of Wundagore or the (always cool) Atomic Steeds will more or less stay the same for years.
