Look at the boxes behind the dolls. This is a bit typical of Pedigree (or perhaps of the time). The same new Sindy Fashion Girl with three different boxes. The left one has the old box design with a new “stuck on label” telling about the new kind of Sindy and which variation of her that’s in the box. The middle one just has the old box and the one to the left has the newer box design.
As a designer and a nature loving person I think the left one and the one below, are a very clever and smart way of using up the old boxes while giving them a new and informative design with just a paper label added!
