Sub Articulo 28.1

	Actually, you can hack this pretty easily.  The method is to
make Fig.1 a column-wide figure at the top of the second column and
Fig.2 a column-wide figure at the bottom of the second column.
	Next, add a null figure with the same height as Fig.2 at the
bottom of the first column (also this "figure" has no caption and
therefore does not mess with the numbering.
	Next, allow Fig.2 to stick out to the left and, finally,
adjust the placement of the figures to make them come out in the
right places.
  For example:
\begin{verbatim}
\begin{figure}[b]
  \vbox to 1in{%              Hack to be as high as the 2nd fig
    \vfil
    \hbox to \columnwidth{%
      \null
      \hfil}
    \vfil}
  \vspace{\abovecaptionskip}
  \phantom{Figure 0: \dots Figure two text\dots}%  Fig.2 caption repeated here.
  \vspace{\belowcaptionskip}
\end{figure}
\begin{figure}[t]
  \vbox to 1in{%		Figure one -- nothing special.
    \vfil
    \hbox to \columnwidth{%
      \hfil
      Actual Figure One
      \hfil}
    \vfil}
  \caption{}
\end{figure}
\begin{figure}[b]
  \hbox to \columnwidth{%	   Fig.2 is one column wide
    \hss                         % but it can stick out to the left
    \begin{minipage}{\textwidth} % and is actually textwidth wide!
      \vbox to 1in{%
        \vfil
        \hbox to \textwidth{%
          \hfil
          Actual Figure Two
          \hfil}
        \vfil}
      \caption{}
    \end{minipage}}
\end{figure}
\end{verbatim}
