Liam Devereux, an illustrator/animator based in London, always sketched scenes from his balcony, which overlooked a garden in his Victorian neighborhood. This eventually resulted in an illustration, and then, something much bigger.
“This resulted in a picture I did called ‘Nighttime’ and spawned a series of works, initially that included the view from my flat but spread to the surrounding area, and further afield,” Devereux says. “Nighttime sold well. Sold out in fact, relatively quickly, but I felt it looked a bit too American and wanted to create something that had a distinctly British feel to it, so I looked at some of the halftone techniques used by DC Thompson and, hey presto, this is the result.”
The illustrations, printed on a Kraft backdrop, evoke a vintage vibe. While it doesn’t carry the vibrancy of the artist’s past work (with an example shown below), the distinct palette of this series is remarkable.
The illustrations of 19-century ornithologist John James Audubon are some of the most influential paintings of nature in both science and fine art. Now, all 435 of his "Birds of America" watercolors are available for free, hi-res downloading. From the American Avocet to the Zenaida Dove, each was produced from hand-engraved plates, works originally printed between 1827 and 1838.

Though the creatures of Claudio Romo are bizarre and at times, frightening, the illustrator’s distinct linework gives each a certain elegance. The Chile-based artist has produced a number of books carrying his strange monsters and plantlife (among them, the beautifully titled “The Book of Imprudent Flora”). Through often carrying no specific timeline, his practice has also extended into the futuristic, as evidenced below.
