# Unexpected vertical bar appearing in leaflet document

I am creating a basic leaflet using the (appropriately named) leaflet package. I immediately ran into the minor issue of an unexplained vertical "bar", similar to the pipe character, being typeset between the first and second columns of the second page. Even the example document and a very minimal leaflet document, such as

\documentclass[10pt]{leaflet}

\usepackage[utf8]{inputenc}
\usepackage[icelandic]{babel}
\usepackage[T1]{fontenc}

\title{Title}
\author{Myname}

\begin{document}
\maketitle
\end{document}


has this bar. (It is visible near the bottom right corner, due to page rotation.)

My question is: What is this vertical bar, and how do I get rid of it?

Did you try the package option nofoldmark? –  Stephan Lehmke Dec 18 '12 at 15:07
Yes, as soon as I realized that this bar was called a fold mark. Of course, this removed it. Thanks. –  Ernir Dec 18 '12 at 15:09
