Hip-hop is a tough game in which only the best survive. From the early days of the male-dominated genre, female rappers have proved that women, though few in numbers, are fearless, strong especially when unified and are not only capable of standing as tall as the next man but also of outshining them. In celebration of Women’s History Month, this 4x6 inch daily flip calendar condenses Billboard.com’s series of web articles, Ladies First: 31 Female Rappers Who Changed Hip-Hop, into daily doses of information. The selected pages show the design system that continues throughout the front pages and patterned backs of the calendar.
