This comic strip originates in the Tumblr chain of attribution at the “Around Since 1991” tumblr, where it is tagged “MyArt”. That Tumblr belongs to Jessi, aka CrystallizedTwilight on DeviantArt. Although the comic strip itself is not visible in the DeviantArt gallery for CrystallizedTwilight, the face appearing in the comic strip also appears as a self-portrait of sorts in the “DeviantID” artist profile section for CrystallizedTwilight.
