The image features a black and white illustration of a smiling mouth with teeth, set against a plain white background. The mouth is stylized with a curved, cartoonish shape and is adorned with a mustache. Above the mouth, there is a text that reads "We're All Mad Here," which is a famous quote from the novel "Alice in Wonderland" by Lewis Carroll. The text is written in a cursive, playful font that matches the whimsical nature of the quote. The overall style of the image is reminiscent of a comic or graphic design, with a clear emphasis on the text and the mouth illustration.
