Prompt
"Generate an image of a large group of dock workers picketing outside the Port of London, with a backdrop of dock buildings and ships, during the London Dock Strike of 1889. The scene should convey a sense of solidarity and determination, with workers holding signs and banners. Incorporate some visual elements that reflect the support of Cardinal Manning and Australian trade unions, such as a banner or a group of people holding Australian flags. The style should be realistic and reminiscent of late 19th-century documentary photography. The image should capture the essence of a pivotal moment in British labor history."
