One of the great all-time ring designs w/no text but attributed to Captain Marvel c. 1946. Also seen once on a jobbers store card with title "Radio Patrol Ring." Done in brass w/adjustable bands and each side has brass lightning bolts against black enamel paint bkg. Top of ring has high relief w/slanted sides and a working compass under glass at top center. Various segments feature rocket control panel buttons as well as several different lightning bolt designs. Brass finish is brighter than usual. Light and very scattered paint wear. Tiny dots off on close inspection but totally clean and visually Exc. Much above average example.
