This is a signal design for the metro system and railroads of Rocaterrania. Also pictured is a fuel pressure gauge design from the driving compartment of the Oriental, the eastbound Metro train.
Personal Significance:
Kuhler himself was a Luddite of sorts (“urban Amish,” as he put it), so Rocaterranians lived in a society where technology, for the most part, had not progressed beyond the Victorian era. When he became a scientific illustrator at the North Carolina Museum of Natural Sciences, he enjoyed playfully merging nature with technology in some of his personal illustrations (e.g., a submarine designed to look like a fish). He also had a gift for creating visual analogies, as evidenced in this illustration.
Influences:
Vintage British railroad signals. Parking meters. Bird specimens an ornithology office at the North Carolina Museum of Natural Sciences where Kuhler worked as a scientific illustrator.
