Via Present & Correct, I was glad to find these gorgeous early 1960s-era science textbooks designed by Rolf Harder.

In a short piece at Graphis magazine not long after these designs were produced, Hans Neuburg wrote that Harder, who won scores of international design awards and has had his work exhibited all over the world, was “among the most significant forces in modern Canadian graphic design.” Born in Germany in 1929, Harder moved to Montreal, Canada in the late 1950s. Online archive Canada Modern has these textbooks as having been designed by Rolf Harder’s firm, beginning in 1964.

These book covers are very strongly reminiscent of the work of painter and illustrator Charley Harper, who looked to field guides to draw beautiful fish and other wildlife for the covers of Ford Times magazine and elsewhere in the early 1950s. I wrote about Harper’s magazine work here at my site in 2017.
