Correct numbering and reference for appendix

Question

In my paper, I tried to create an appendix and refer to it from the main text.

I tried to post it a very easy example. It does not depend on the journal class thus I don't know what's wrong with this simple syntax.

\documentclass[a4paper,10pt,draft]{article}
\usepackage{pslatex,graphicx}

%opening
\title{bla bla}
\author{a, b, c}
%
\begin{document}
%
\maketitle
%
\begin{abstract}
ipse dixit 
\end{abstract}
%
\section{ introduction}
%
In Figs.~\ref{figA1}, \ref{figB1}, \ref{figC1}
% Should be: In Figs. 1, 2, 3
\section*{Appendix}
%
\appendix
%
\begin{figure*}
 \centerline{\includegraphics[width=0.2\textwidth]{figureB1.png}}
 \label{figA1}
\caption{Ipse dixit...} 
\end{figure*}

\begin{figure*}
 \centerline{\includegraphics[width=0.2\textwidth]{figureA1.png}}
 \label{figB1}
\caption{See Fig.~\ref{figA1}.} %Should be "See Fig. 1" 
\end{figure*}

\begin{figure*}
 \centerline{\includegraphics[width=0.2\textwidth]{figureC4.png}}
 \label{figC1}
\caption{See Fig.~\ref{figB1}.}  %Should be "See Fig. 2"
\end{figure*}

\end{document}

I add two explicative images here:

shows the numbering in the main part of the text. Which should be "1, 2, 3" not "1, 1, 1" and the

shows the reference calling in the appendix itself which, again, is wrong.

Many thanks in advice for your help.
