The self-explanatory text for this
advertisement is complemented by a striking illustration that shows every
conceivable form of transportation in the early 1940s,
while a Dzus fastener circles the globe. These devices were indeed
ubiquitous, but they are best known for securing
aircraft cowlings in place.
The staggering variety of these
fasteners is only hinted at. Ukrainian-born inventor William Dzus
filed 32 patents during his career in America and over 6,000 variations had been
developed by the time of his
death in mid-1964. The thunderbolt in the upper right
corner of the poster indicates that "Dzus" is pronounced like the name
of the Greek deity Zeus.
