# Customising titlepage created as a separate tex file outside main

Without using the \maketitle, I'm creating a separate file for title page named titlepage.tex and invoking it in the main.tex. I would like to customize the header only for this separate TEX file, to add logos in the title page header and I'm unable to do so. I'm using the following code:

\begin{titlepage}
\begin{center}
\vspace*{5cm}
\begin{huge}
\textbf{Thesis Title}
\end{huge}\\
\vspace{1cm}
\begin{large}
Master Thesis Submitted By\\
\vspace{0.5cm}
\textbf{Max Mustermann\\}
Matriculation Number: XXXXXX
\end{large}\\
\vspace{2cm}
