Completed by Andy Warhol in 1985, the Reigning Queens series includes Queen Beatrix of the Netherlands, Queen Margrethe II of Denmark and Queen Ntombi Twala of Swaziland. Warhol depicts these four female monarchs in their own right, rather than as women who were married to a king. The loud and vivid use of color draws attention to the subject and creates a solid movement around each of the portraits. Warhol created the Reigning Queens series during the mid-1980s, arguably his most prolific period. The portfolio consists of sixteen screenprints.
