The woman is wearing a white dress and has her hair tied up in a bun, while the man is wearing an apron and a hat. Both of them have a determined expression on their faces, as if they are ready to take on the challenge of washing their hands. The text on the paper reads "Gold Dust Washing Powder" in bold, black lettering.
