Very Nice example of the NSFK Flight Prize Badge. The badge is of nice quality, construction and manufacture. The NSFK emblem is to the top. Around the edge, it has inscribed For the great flying day in Frankfurt, roughly translated. This was sponsored by the NSFK group 11. A very nice badge to find. An illustration can be found in the book "NSFK, Uniforms, Organisation & History" by John R Angolia, David Littlejohn on page 445.
