The world inside...

These illustrations are stunning. I found them today and had to share. They are botanical microanatomy plates by Frederik Elfving. He was a professor of botany at the University of Helsinki. "Anatomia Vegetal" was published in 1929. I could spend so much time looking at the details of each plate. These really are a designer's dream. I find loads of inspiration for shape and pattern, line and scale. Beautiful and humbling.
