2.75x4x1” deep original mailer from 1954 has a little surface paper off the blank underside and one blank side panel but overall is structurally very sound and very clean. The mailer holds emptied package that originally contained baking powder. It also holds a two-page photocopy of the original 8.5x11” instruction sheet which came with the set explaining use of the figures and with additional commentary on U.S. Navy frogmen. The figures themselves are each about 3.5” tall, Mint and unused and designed as “Obstacle Scout, Demolitions Expert, and Torch Man.”
