My partner designed this amazing colouring page as a birthday present for me and included the right to publish it.
It's full of surprises and tiny details, but fortunately he does not expect me to finish colouring it any time soon. :)
The original drawing is a full A4 page (8.27" x 11.69"), and in order to preserve the details I've kept the image in the PDF as large as possible. When printing on US Letter, you'll need to scale the page to fit the paper, so it will be slightly smaller.
