Know your legends related, but me personally I have no idea. Metal head badges came onto my radar a few years back when I bought a 50's Indian Motocycle bicycle, and the bike had an amazing raised metal Indian chief head badge, and in my research of the bike I came across the female version which had an Indian squaw. To me this is the cherry on top finish to the overall stylization of a bicycle, and with the right logo, shape, colors, and name it could be a design that withstands the true test of time. These beautiful pieces of cycling folklore capture everything that I love in about a 1" by 3" piece of tin.
Know your legends...Don't be bashful, please do enlighten us!!!
