Weege was a pillar in the printmaking and papermaking fields of the United States. Though his style changed to abstract, his early work, made during the Vietnam War, commented on social and political issues through graphic Pop art imagery. Around this time, he was also making prints based off of songs. Aquarius/Let the Sunshine In is a medley of two songs written for the 1967 musical "Hair." The lyrics were based on the astrological belief that the world would soon be entering the Age of Aquarius, an age of love, light, and humanity, the perfect theme for Hair and its commentary on the Vietnam War. Critics wrote that, with Hair, a new age, the Age of Aquarius, had dawned. This was to be an age of peace and harmony, of love, an age that would abolish war and racial discrimination, aggression, and crime. These were themes that Weege agreed with and portrayed in his work, using color as the vehicle to express them
