Dummy versions of 11 published and 2 apparently unpublished titles illustrated by Jones. These dummies are preliminary layouts showing the size, shape, form, and general style of the final printed versions of each title. In many cases, Jones made up the dummy versions using notepads and exercise books. Some of the dummies feature printed text pasted into position alongside finished illustrations, others are clearly early roughs, with rough hand-written text and draft illustrations. All of them are complete in content, although some are missing front covers.
As few of the dummies are dated, they are arranged in chronological order according to the first date of publication for each title, with the apparently unpublished titles at the start of the series.
