One of the great all-time ring designs w/no text but attributed to Captain Marvel c. 1946. 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. Only a couple of pinpoint dots of paint are gone. Great example. Exc. and scarce.
