The above cover is the original released with the first edition of the book in 1982. The artwork was designed by illustrator Caroline Holden. Holden specialises in children's book design and is an author herself. This cover became so popular she was eventually commissioned to design the covers for the rest of the series. It was specifically requested for Holden to refrain from including the characters on the book covers, instead using objects and possessions to give a sense of personality. The coloured pencil style alludes to the idea that this a book for younger readers, without being too childish. There is a lack of bright garish colours usually seen on children's books, which again appeals to a young adult audience.The style of drawing is also similar to popular political cartoons at the time, which relates to the context of the book. The typeface is hand drawn and relates to the idea that the book is a diary and has a very personal and relatable narrative. The mirror plays a key part in making the book appealing to a wide audience - readers can almost see themselves in the mirror and empathise with Adrian as a character.
The above cover was illustrated by Roderick Mills and has a very hand-rendered style to it. This is the simplest of all existing covers for the book, with minimal imagery and no/neutral colour. Because this is the 30th anniversary edition, the overall design is very nostalgic and historic. This particular cover would not appeal to a younger audience and is located in the adult reading section of the book shop. The broken glasses relate to Adrian's troubles as a teenage boy, how he got bullied and the working class background of his family. This could also represent the state of the NHS at the time. The typeface used is traditional but with a hand-drawn feel to it, keeping it friendly and relatable whilst also appealing to an older audience. The overall cover would not appeal to younger children as they would be unlikely to even look at this on a shelf, in comparison with other bright and inviting book styles. This furthers the idea that the book can also appeal to an older and more mature audience.

The above cover was designed by illustrator Joe Berger, who has also drawn for many other children's books such as Superhero Dad. Berger's certain style for children's illustration is the reason for the way this cover has been designed - perhaps a little too immature for the intended audience. This cover would stand out more on a shelf against the other two covers, but appears to have been designed with a younger audience in mind. Unlike the other covers, this one features a person - yet the face is still hidden to add an element of mystery. The reader can imagine themselves in Adrian's shoes. The typeface is very hand-drawn, again alluding to the diary style and personal narrative. Personally I feel this cover is inappropriate and not very well suited at all for the book's content. It appeals to a younger audience than the book is intended for.
