The 15th of August holds significant importance in the history of Bangladesh, marking the tragic assassination of Father of the Nation, Bangabandhu Sheikh Mujibur Rahman, in 1975. On this day, banners play a crucial role in expressing national grief and remembrance. Effective banner designs for Mourning Day typically feature a somber color palette, predominantly black and white, symbolizing loss and sorrow. Imagery of Bangabandhu, often accompanied by the national flag, serves as a poignant reminder of his legacy. Additionally, incorporating powerful quotes or messages of remembrance enhances the emotional impact. These designs not only honor the memory of those lost but also unite the nation in reflecting on its past, emphasizing the importance of resilience and unity in moving forward.
