textblock* on every page

I have following:

\begin{textblock*}{15mm}(191mm,20mm)
\begin{spacing}{6.2}\noindent\thin\color{black}
{\fontsize{50}{60}\selectfont
M\\
Y\\
T\\
E\\
X\\
T}
\end{spacing}
\end{textblock*}

And I have a longtable:

\begin{longtable}[ht]{p{.37\textwidth} p{.518\textwidth}}
....
\end{longtable}

This longtable will go over two - three pages and I want my textblock displayed on every page, where this longtable will be continued. Currently it is only displayed on first page. (Code above is in a separated file "file.tex")

My code:

\documentclass[a4paper,10pt]{article}
\pagenumbering{gobble}
\usepackage{fancyhdr}
\usepackage{graphicx}
\usepackage{eso-pic}
\usepackage[absolute]{textpos}
%\usepackage[T1]{fontenc}
%\usepackage[utf8]{inputenc}
\usepackage{listings, mdframed}
\usepackage{color}
\usepackage{fontspec}
\usepackage{xunicode}
\usepackage{xltxtra}
\usepackage{setspace}
\usepackage{tabularx}
\usepackage{longtable}
%\usepackage{xcolor}
\usepackage{lmodern}

\begin{document}

\include{content/file}

\end{document}

In the file.tex is only the textblock* and longtable. Nothing else.

EDIT:
As a workaround I have solved this by defining it in header. So I use
