Rather surprisingly, none of the four volumes of this set, nor the box itself, mentions Gyles Brandreth as the author, though the title page of each tiny book records “Illustrated by Judy Brown (see also www.judybrown.co.uk ) . [I wonder if these tiny books – each 64 unnumbered pages - are based on some other Puffins with the same title but in a normal Puffin size?]
The different ISBN numbers (using a standard Puffin numbering formula 0 14 03 xxxx X) are given for each book, but a different ISBN number 0-14-095322-1 is used on the bottom of the box, which is also the only place where the price (of the boxed set) is given: U.K. £2.95 Aus. $6.95 (recommended) Can. $5.95 N.Z. $9.99 (Inc. GST).
An attractive feature is that the progressively serious emergencies indicated by the four titles “Help!”, “Help! Help!”, “Help! Help! Help!” and “Help! Help! Help! Help!” are reflected in the different front and back covers of each of the four books, the front showing a boy more and more core completely bandaged and the back cover showing a girl clinging with increasing desperation onto a cliff-top before finally losing her grip.
The automatic boxes from the Library Thing website indicated height, length and thickness all as 20 inches, which made no sense, so I have substituted my own measurements (for the box itself). These are the tiniest Puffins in my collection. Each of the four books measures 7.9 x 5.9 x 0.6 cms

Each book has a bookplate or identifies the owner. For example “Help!” haS opposite the title page:

THIS EMERGENCY JOKE KIT BELONGS TO:

The jokes vary from Christmas cracker putrid puns to inspired zanity . Here’s one joke from each of the four books:

What do you call a cat who has swallows a duck?
A duck-filled fatty puss.
What’s the difference between a cat and a match?
One’s light on its feet, the other lights on its head.
What should you do with a cat that’s lost its tail?
Take it to the retail shop.
What’s black and white and makes a lot of noise?
A zebra with a set of drums.
