The first image is a limited edition print (3 of 5) which is signed by both the ballerina and Mr Riley. It is extremely rare.
The second image is a first study prior to going to camera and print and is covered with Mr Riley's annotations.
The third image is similar to the second but it is the 3rd and final study, again with Mr Riley's annotations, prior to going to camera and print.
