From the trenches to the home front, soap played a pivotal role in history. During WW1, Wrights Coal Tar Soap became a trusted companion for soldiers, providing relief and cleanliness amidst the chaos of war. In 1900, Gossage Soap captured hearts with its captivating advert, leaving an indelible mark on society's consciousness. However, not all soap advertisements were progressive. The racist Pears ad serves as a stark reminder of past prejudices that we strive to overcome today. Yet amidst these dark moments, Port Sunlight emerged as a beacon of hope - a workers utopia built around the production of soap. The power of advertising was evident in posters promoting Sunlight Soap at every corner of London's bustling Piccadilly Circus in the 1920s. Inside tramsheds like those found in Lytham St Annes, Lancashire, people would catch glimpses of Thoms Castile Soap cards enticing them towards cleanliness and luxury. Across borders, French artist Jean Carlu created an iconic advertisement for Monsavon soap in 1925 - showcasing both artistic brilliance and effective marketing strategies. Meanwhile, Pears Soap continued to captivate audiences since its groundbreaking advert back in 1887. As time progressed into the 1930s, Goodwins toilet soap brought elegance and sophistication into households worldwide. Through wars and societal changes alike, one thing remains constant - soap has been an essential part of our lives throughout history.
