Jim Hoy, author of “Flint Hills Cowboys: Tales of the Tallgrass Prairie,” will sign copies of the book from 7 p.m. to 9 p.m. Friday at Fields Gallery, 712 Mass.

Local artist Louis Copt, who created the cover art, will be presenting new prairie paintings.

Hoy’s work focuses on the oral history of people who have lived and worked all their lives within the open landscape of the Flint Hills.

Copt’s landscapes are spare, with sky being as large and centrally important as land. Luminous in color, time flows across these vistas in stately vibrancy.
