It's possible you're thinking of a different aspect of the story or maybe you're remembering a detail from another source.
Here's what August does put on her honey jars:
* "August Boatwright's Honey" label: This is the main label on the jars, emphasizing August's name and the product.
* A drawing of a bee: This simple image adds to the overall aesthetic and reinforces the theme of bees and honey.
If you have any other details about this "black Mary" image, perhaps from a different source, let me know and I can try to help you further.
