May I first suggest you reduce these to around 5mm in width then marvel at how extraordinarily accurate these Pantone Swatch Albums are by David Marsh. There are many more examples over on David’s website.
I was loading up the images in WordPress (see below) when I saw the tiny tiny thumbnails. Pretty damn incredible.
David explains to DesignBoom: “The purpose of this series is my own exploration and development along with the satisfaction I have when I complete an image I like to experiment with image creation and will stumble onto a technique and develop that and then archive it and resurrect it when I have a purpose for it. I will develop this idea into various new directions, the next being actually painting some of the covers that work best, hopefully on a very large scale or using collage to create the image. the options are endless and that excites me.”
