caption: The image shows an open book with a black and white image of a man's face on it. The text on the paper reads "From Thomas Vinn, Esq. to Mr. Ching, Apothecary, Ching's Patent Worm Lozenges". The man in the image appears to be looking off to the side, with a thoughtful expression on his face. He is wearing a white shirt and a black hat, and his hands are clasped together in front of him. The background of the image is a light blue color, and the text is written in a bold black font.
