This piece is a mosaic created with Venetian glass tiles. The mosaic technique utilizes small square colored tiles—usually of stone, glass, shell, mother of pearl, or other materials—known as tesserae that are assembled into a pattern, design, or picture. Mosaics appeared as architectural elements in both interiors and exteriors beginning in the 4^th century BC. They have continued to evolve in diverse cultures separated by time and geography.

Midcentury designers Evelyn Ackerman and Sherill Broudy created this work together. Ackerman, along with her husband Jerome, was active in Los Angeles and produced affordable and accessible designs for homes and offices; Broudy was an architect and a former classmate of Jerome Ackerman and later became a business partner with the Ackermans. The Ackermans' work, reflecting a modernist sensibility, included ceramics, mosaics, textiles, woodcarvings, hardware, and metal. From 1954 to 1976 their work was shown in every exhibition of the prestigious California Design series held primarily at the former Pasadena Art Museum. Pennants was shown in the 1959 exhibition.
