Over the past few years, Mike Maihack’s adorable Batgirl/Supergirl comic strips have become a holiday tradition. Today, the creator of Cow & Buffalo and Cleopatra in Space is back with a new Christmas edition, in which the eternally cheerful Maid of Might wants to go caroling in Gotham. Which is apparently a lot like trick-or-treating ...

"I feel like every Batgirl/Supergirl comic I’ve drawn so far has led up to this one right here," the cartoonist writes. "Anyhow, Merry Christmas, everyone! I hope everyone is okay if this is the last of these for a while. 2015 is going be a busy, busy year for me."

Mailhack is offering the original art for sale on eBay. You can find previous strips on his blog.
