Interestingly, it showed up twice in my e-mail. The first time, it was in a vertical format, but squished, and then right below that, it was in the 4 panel layout linked above.I also got two copies of The Argyle Sweater, and unlike the two layouts for Lio, both were exactly the same.Very weird.
Your comment reminds me of this comic:
