Bigger on the Inside

Looking over early Legion comics, I realized something.

Beginning with the first Legion story in Adventure 247 (April 1958)—and certainly by the start of the Legion's first continuous run in Adventure 300 (September 1962)—the Legion's "Super-Hero Club House" was inexplicably bigger on the inside than it was on the outside.

Doctor Who premiered in November 1963.

I'm just sayin'....
