Knowledge advances incrementally, one step or Tidbit at a time, and an example of that incrementalism is our understanding of the whens and whys of winged helmets. I previously published Tidbits about winged helmets, noting that they originated in 1930 to better pad the front of helmets and protect the foreheads of the era.
Wow. What an education this catalog has given us all! Love the Mercury style. I hope someone comes up with a game used image.
