“A Music Day” (2 ½ in x 3 ¼ in) is a silver gelatin albumen print taken on the Mall in Central Park in 1867. The Music Pavilion designed by Jacob Wrey Mould stands in the center of the image, cut from page 41 of the Eleventh Annual Report of the Board of Commissioners for the Central Park, for the Year Ending December 31, 1867. New York, Evening Post Steam Presses, 41 Nassau St. Cor. Liberty, 1868. A remarkable image, showing the musicians in the Music Pavilion, and an audience of well-dressed ladies and gentlemen, some standing, some seated and some dancing as their motion is captured in the image. Condition fine. Jacob Wrey Mould (1825-1886) designed Belevedere Castle and Bethesda Terrace, two examples of high Victorian architecture, as well as the Music Pavilion. To the latter, Mould’s skills as a pianist and organist informed his design. He is buried in Green-Wood Cemetery in Brooklyn. Fine condition of a strong image.
