Does anyone have any information on the "chicago style" of reflective decals on leather fire helmets. Meaning: Instead of the yellow trapezoids on the helmet, the helmet has yellow 1x4 bars placed vertically on each side of the main ribs in the back and sides. Anyone ever heard of this or where it comes from or the tradition? Ive been doing this for years and it is a great look but I want to know where it came from. Im pretty sure it is a chicago thing but cant find any info on it. Any ideas??? Thanks
