Pin-Up Culture refers to a style of art and photography that became popular in the early to mid-20th century, particularly during the 1940s and 1950s. It features images of attractive individuals, often women, posed in a way that emphasizes their physical appeal. These images were commonly used in calendars, magazines, and posters, serving as a form of entertainment and fantasy for viewers. The term "pin-up" originated from the practice of pinning these images on walls or bulletin boards. Iconic figures in this culture include Betty Grable and Marilyn Monroe, whose images became symbols of beauty and glamour. Pin-Up Culture has influenced fashion, art, and media, continuing to inspire contemporary styles.
