Well, I had to do some searching to have enough info to tell you something about Jayne hats. First there was a TV series named Firefly, then came the movie Serenity, then there were comic books that filled the gap between the two. The best I can explain is that there is a man named Jayne who wore this hat. Everyone knew that a man who wore that hat must not be afraid of anything. That's what I know.
Then there are Kitty and Paulette who volunteered to make Jayne hats as "door prizes" for the blood drive at the Pittsburgh Comicon. The blood drive is on the 16th of April. The comicon is Apr 15-17 at the Monroeville Expomart. So give blood to win one of 4 Jayne hats!
Kitty is modeling one of the hats. I don't know if she isn't afraid of anything, but she sure is a good sport.
