Mazes in puzzle books that used Interstate and U.S. route shields

[bandit957]

Anyone remember these?

I remember in the late '70s, you could get little books of mazes at drugstores. I remember that some of the mazes were full of little Interstate or U.S. route shields. The shields didn't have numbers. They were blank shields, and the paths of the mazes wound all through them.

Does anybody else remember this?

Is it one giant sign with little lines inside it?

Nope, they were a bunch of tiny little shields.

Any pictures? I've no idea of what you're talking about.
