This would be something the Boomer generation grew up with, and I think maybe the previous generation too.

They are named after President Lincoln, but only as a marketing tactic to use some of his reputation, there's no real connection.

I would imagine even some native English speakers are learning something with this post. I haven't seen them in a while.
