The series of 16 images were photographed by Bill Eppridge, but only one of the images was actually used in the original story. The photos capture Minnelli alongside her then fiancé Peter Allen, as well as members of the Flora creative team including co-star Bob Dishy, choreographer Lee Theodore, Hal Prince and George Abbott.
