This is a Right Face puzzle.

(See 294 for info about this “reject” series.) In a very early draft that poor glmathgrant suffered through — seriously, you will pity him when I finish airing out the dirty laundry — this was the Right Face adult, with Wednesday’s puzzle being the baby at the time. “MellowMelon, what the hell were you thinking?!” you might rightfully say. You’re probably going to say the same thing for the next several Fridays, actually.
That said, the puzzle probably feels right at home on this blog, which is brutal relative to a timed contest.
Other bit of trivia: First ever Right Face larger than 10 by 10 by anyone, at least to the best of my knowledge.
