Hippie culture tattoos often feature symbols like peace signs, flowers, and mandalas, which represent the values of peace, love, and unity that defined the 1960s counterculture movement. These tattoos serve as a visual representation of a person's commitment to free-spiritedness, nonconformity, and a desire for social change. By wearing these symbols on their skin, individuals are able to express their allegiance to the ideals of freedom, creativity, and self-expression that hippie culture embodies.
