Who's behind the striking 'Stop War' poster that's all over social media? It turns out it's Barbara Galińska, a talented calligrapher from Warsaw, Poland. Her design, with its simple yet powerful two-tone black and red typography, has struck a chord, not just online but in real life too.

The poster's influence extends beyond the internet; murals based on her design have popped up in Brooklyn and Switzerland, and children in Italy wear T-shirts featuring the graphic. Galińska explains that she created the work for an international calligraphy challenge, aiming to address global issues through art.

In a statement about the piece, she says: 'Strong black and red colors immediately attract attention. And the unusual structure of the letters encourages longer observation and reflection.' Her hope is that this design will become a universal symbol of peace.

Despite her realism about the poster’s potential, Galińska’s work has certainly made waves. With such widespread recognition, could it truly transform our approach to peace or simply highlight the ongoing issues?
