Signature description at the bottom of a document

Question

I want to put a description which signature goes where and who signed there at the bottom of a document. For the moment I use \vspace with a hand-chosen value that brings down this stuff to the bottom. But of course this is not an elegant solution, and I am sure one can do much better ;)

Here is a minimal example:

\documentclass{article}
\usepackage{blindtext}
\usepackage{multicol}

\begin{document}
\blindtext
\vspace{80mm}

\setlength{\columnsep}{2cm}
\begin{multicols}{2}
Person 1
\vspace{30mm}

Person 2\\
\columnbreak

Person 3
\end{multicols}
\end{document}

Answer 1

You should use \vfill.

\documentclass{article}
\begin{document}
Top content...

\vfill

Bottom content.
\end{document}
