Young Edison Lee is Danny Dunn (from my childhood) crossed with Bill Watterson’s Calvin (from my kids’ childhood), complete with a time machine (which both Danny and Calvin also had). The first appearance I saw was in 2012, although it wasn’t until 2014 that the real travelin’ seemed to start, with a trip back to 1972.

Even then, though, I almost put the whole thing into the it’s-only-in-his-imagination category, but what could possibly be more real than a kid’s imagination?
