The image features a round, vintage-style sign with a beige background and a darker brown border. The sign prominently displays the words "ARSENIC POISON" in a bold, serif font. Above the text, there's a small illustration of a bottle with a dropper, suggesting the poisonous nature of the substance. The overall design of the sign gives it a classic, perhaps antique, appearance. The sign is likely used to indicate the presence of arsenic poison in a particular area or product.
