# header with logo on first page only of documentclass article

I am writing an article with a header on the first page only; the header includes a logo. Here is a MWE using fancyhdr:

\documentclass[a4paper]{article}
\usepackage{fancyhdr,graphicx}
\usepackage{lipsum}

\pagestyle{plain}
\fancyhf{}

\includegraphics[width=32mm]{example-image-a}}}

\fancyfoot[C]{\thepage}

% \title{\flushleft{This is the title}}
% \date{}

\begin{document}
% \maketitle

\section*{A section}

\thispagestyle{fancy}
\lipsum[1-7]

\end{document}

With this approach, the text on page 2 starts below where the header would be if it were included on this page.

How do I get the text to start at the "top" of page 2 instead?

Don't consider the content at the top of page 1 as being a header. Instead, set it as part of a regular document. That way you don't have to worry about influencing the header space (or \headheight) and how it may affect subsequent pages.

\documentclass{article}

\usepackage{graphicx,lipsum}

\begin{document}

\noindent
\begin{tabular}[t]{@{}l}
\end{tabular}
\hfill
\raisebox{\dimexpr.8\baselineskip-\height}{\includegraphics[width=32mm]{example-image}}

\section*{A section}
\lipsum[1-7]

\end{document}

The above solution is independent of fancyhdr or geometry, so you can add that without affecting the resulting output/layout.

A simple patch could be the following:

\documentclass[a4paper]{article}
\usepackage{fancyhdr,graphicx}
\usepackage{mwe}

\fancypagestyle{fancylogo}{%
\fancyhf{}%
\parbox[t][0pt][t]{.6\textwidth}{%
\large \textsf{%
}%
}%
}%
\parbox[b][0pt][t]{.3\textwidth}{%
\includegraphics[width=32mm]{image-a}%
}%
}%
\fancyfoot[C]{\thepage}%
}

\begin{document}

\vspace*{24pt} % or whatever is needed

\section*{A section}
\thispagestyle{fancylogo}
\lipsum[1-7]

\end{document}

A neater solution could make use of the geometry package to change the page layout of the first page, but for a simple situation like this I think it would be overkill.
