I recall finding out that this image comes from a German comic, but its name is lost on me. I've tried a reverse image search on Google, but with no luck. Could someone please tell me the name of the comic, and more about the story? I'm especially curious to know how it ends. Thank you.
After searching enough, I was able to find an answer to my own question: this comes from the German comic horror series Gespenster Geschichten. This image comes from the story called "Die Uhr des Sensenmannes" (The Clock of the Grim Reaper), from issue 1570.
For the curious, from what I could gather, the young woman in the image has a dying father. When the Grim Reaper comes to claim him, she manages to steal the hourglass that represented his time, and make the Grim Reaper spare her father. She then puts the hourglass atop a few books on a table, but rats come in and flip it, causing time to rapidly turn backwards for the young woman. This causes her to get younger until she vanishes, at which point the Grim Reaper comes back to collect his hourglass, and claims the father's soul offscreen.
