Wrinkles can tell a story through the experiences they represent. For example, laugh lines around the eyes might show a life full of joy and humor. Frown lines on the forehead could indicate times of stress or worry. And wrinkles around the mouth might be a sign of years of talking, eating, and expressing emotions.
I'm not sure specifically as I haven't read it. But generally, a graphic novel might be about various things. It could be about the life experiences of characters, perhaps dealing with themes like aging which might be related to 'wrinkles'. It could also be a fictional adventure where the concept of wrinkles has some symbolic meaning within the story.
The real story of Wrinkles the Clown is that he was created as a creepy character. He was known for showing up in kids' bedrooms at night in a really spooky way, which was part of a marketing ploy to make him seem very mysterious. Some say it was all just a way to scare kids for fun and create a local legend.
They can tell a story of emotions. For instance, if someone has a lot of wrinkles around their eyes from smiling, it indicates a life filled with happiness and positive interactions. On the other hand, deep wrinkles on the forehead from frowning might tell of a life with some stress or worry.
