This is how a showcase post might look.
Some thought will need to be given to the order that books are placed; even if un-numbered, people may assume the book listed first was the winner.
Option one is an image carousel (perhaps these look too small):
Caro Was Here
Designed by Gayna Murphy
Published by Walker Books
Rationale: This design was about paring back the details to create a striking cover using a visual symbol as a graphic device and bold type design styling. Danger and adventure in one! Due to budget constraints we use stock images a lot, so when I chanced upon this image of a match and finger I knew it was perfect for this book. The title lettering I distorted in illustrator to give it a letterpressed feel to tie in with the image. The secondary font assisted with the visual story. Using few colours makes for a striking cover design.
Option two is the images could be listed individually:

Or Option 3 is a combination of the two:

Earth Hour
Designed by Sandy Cull
Published by UQP
Rationale Referencing earthy themes; the garden, soil, the quiet, blue stillness often referred to as the ‘blue hour’, I presented images of cyanotype flower pressings and shimmery, blue light. I found some mono versions amongst Garima’s brightly coloured textile prints. These whispery, fragile, translucent leaves glowed and shimmered; and Garima didn’t mind my colouring them the blue in my minds eye. It called for fine san serif type – nothing too loud or dominating. A follow-up to ‘Typewriter Music’, the specifications were predetermined but these were perfectly suited. I designed the text with these principles in mind also.
