Thanks for the information guys. Okay, I know now what a "spider cap" is. I've seen them a lot, like you said, on police cruisers. That's the look I'm going for, but I didn't want anything that looked modern. I'll check out Moon, et al.
Shark, to let you know, one of my prized possessions is a vintage Masillon Tigers football t-shirt. It's orange with the tiger in an old-style helmet running with a football.
