Final answer:
Hergé added realism to his comic characters by using detailed research, clear line styles, meticulous detail, and drawing inspiration from real-world events and locations, making the adventures of Tintin believable and relatable.
Step-by-step explanation:
Hergé, the Belgian cartoonist best known for creating Tintin, added a touch of realism to his comic characters by meticulously researching his subjects, incorporating international settings based on real locations, and using detailed and accurate designs for both characters and backgrounds. He emphasized clear line styles and used meticulous detail in his drawings, which allowed him to create a believable and immersive world for his readers. This approach was quite distinctive when compared to the abstract styles or the more fantastic elements found in other comics of his time.
To further enhance the realism in his comics, Hergé would often draw inspiration from contemporary events and cultures, adding an element of social commentary to his stories. This method of incorporating reality into his work helped to ground the adventures of Tintin in a world that readers could recognize and relate to, raising the credibility and appeal of his narratives.
