Complete kit consisting of five pieces (including envelope) from 1948 and all are the final versions made for this club. Envelope is the only version of the four produced that actually pictures the badge along w/the club name at top left. Envelope shows heavy and obvious moisture staining and is just Good. 1.5" tall metal badge is the second version and has small style lettering. Scattered aging, but this mostly shows as nice patina highlights. VF. Club letter has the briefest text of the four produced. 8.5x11" certificate is one of five different versions produced, this is the only one to feature Black Canary as part of the DC Comics characters shown. Has typed/penciled name/address on appropriate lines as intended (matching name on envelope). Both have obvious moisture staining and are just Good. Cardboard decoder is designed as a folder rather than a wheel as in earlier kits. Reverse includes code chart and has been signed in ink on appropriate lines and folded along scored line as intended. Even lt. aging and lesser degree of moisture staining. VG.
