His teepee preference once almost got him in hot water decades ago when, as a judge, an inmate sued him, alleging the judgment against him was invalid because Poe had signed it with a tent drawing rather than his name.

The five-term congressman recalls while the court considered his signature “quirky,” it ruled the teepee stood as an acronym for Poe and could be used.

But court ruling or not, Poe’s signature still won’t fly in Congress. The lawmaker says, “The House, however, when I do the voting part, they require the actual six-letter mess.”

Poe’s peculiar John Hancock has now become a staple of not only his writing, but of his wardrobe.

“On my boots that I wear I don’t have my initials, I have a teepee. And then on the sleeve of my shirt where normal people put initials, I have a teepee,” he explains with a hearty laugh.

Remembering when the idea to draw a teepee came to him years ago he says, “Sure enough, I stuck with it.”
