Back in the 50s and 60s Kryptonians wore colorful jackets and tights emblazoned with emblems of one kind or another - Jor-El's being a stylized sun. So yeah, the tradition does go back a ways.
I still miss the transparent plastic rings the Els and their countrymen wore instead of hats during the Wayne Boring days. I don't see why successive generations of artists haven't understood that these were absolutely essential
to the Superman mythos.
