In these reruns, they've removed the handwritten date that Chip put in the gutter and replaced it with a typed date somewhere in the panel, here, in the first panel under the fireplace. So far, none of the dates have matched up so it makes sense to replace them. This is the first strip where the date lines up--this strip first appeared December 24, 2018 and is being printed again December 24, 2021. But they still removed the 12/24 date from the gutter and typed it in anyway.
Anyway, the real gift isn't a gift at all. It's pointless attention to detail. Merry Christmas.
