This is one of only five examples we've offered in five decades. 1.25" with no maker's name issued in 1941 to the relatively few readers requesting to become a "U.S. Jones Cadet" and who received a "National Emergency Kit" consisting of this membership button, a decoder and additional membership materials. The various items are detailed in Hake's Pop Culture guide where this button is the lead off item as USJ-1. having values in Good, Fine, and N. Mint as $1250.00, $3500.00, and $6000.00. The front of the button has three tiny and very faint age dots on the upper left rim edge. The button has perfect centering and full gloss with intense color. Among the very rarest comic book premium buttons.
