caption: The image shows a poster featuring a painting of a man and a woman, with the text "The Ault & Wiborg Co. - Makers of Fine Printing and Lithographic Inks" written across the top. The painting depicts a man wearing a top hat and a long coat, and the woman wearing a dress with a high neckline and long sleeves. Both of them have a serious expression on their faces, and their hands are clasped together in front of them. The background of the painting is a deep blue, with a few stars twinkling in the night sky.
