Lois S. Keeler is notable for developing her own pastel stencil technique wherein she would brush pastel pigment through celluloid stencils with her own hand-made brushes. Each delicate composition is meticulously assembled piece by piece and accented in pencil and watercolor. In 1937, Carl Zigrosser of the Weyhe Galleries/NYC was instrumental in Lois Keeler’s progressive success as an artist when he chose Light and Shade from her works exhibited in his gallery for the American Artist Group's Christmas card that year. Having lived primarily in both Chicago and Colorado, Keeler moved to Seattle in 1942 with her husband and fellow artist Harold Keeler who was offered a job at Boeing during WWII. As with Colorado, Washington provided a wealth of natural beauty that inspired both artists. Since her passing in Lacey, WA in 1997, her delicate pastel stencil "poems" have continued to delight.
