From Buckles

Another shot of Peggy, Mack and "Opal"duing this period. Odd there's no headpiece, years later when I worked her she would reach up and take hold of the front strap, squeeze it tightly and hold her breath until she heard the command "Alright!" then release the strap as she exhaled. To dismount she turned to her left, stepped down to the lower step with her front feet and somehow managed to swing both hind legs around and go into a sit-up with her back feet positioned on the lower step.
