Adding a figure containg multiple figures inside \twocolumn optional argument

Question

I read here that you cannot add a \begin{figure} inside of the optional argument for \twocolumn.

I want to add a row that contains 3 images in a twocolumn document.

\twocolumn[{
\begin{@twocolumnfalse}
\maketitle

  \begin{figure}[h]       
  \fbox{\includegraphics{fig1.pdf}}   
  \hspace{30px}
  \fbox{\includegraphics{fig2.pdf}}
  \hspace{30px}
  \fbox{\includegraphics{fig3.pdf}}
  \caption{this is the caption}
  \label{materialflowChart}
  \end{figure}

  \begin{abstract}

  \end{abstract}
\end{@twocolumnfalse}
}]

Since I cannot use \begin{figure} to create my figure, how would I create a row of figures to add inside the \twocolumn ?

Decided to skip the \begin{figure} part and just use \includegraphics and that worked. — martin36, May 17 '16 at 14:09
@ChristianHupfer I tried what you suggested, but got the error: "Extra }, or forgotten \endgroup." — martin36, May 17 '16 at 14:10
Alright, apparently that works for the twocolumn option mode only, but not for \twocolumn command — , May 17 '16 at 15:31

Just drop those dreadful figure environments -- if it is not meant to float anyway, just use \includegraphics and a \captionof{figure}{caption text}\label{foo} etc.

\documentclass{article}

\usepackage{graphicx}
\usepackage{caption}
\usepackage{blindtext}
\title{Theory on Ducks}
\author{Paulo Roberto Massa Cereda (PhD. in Duckumentation)}
\begin{document}

\twocolumn[%
\maketitle

 % \begin{figure}[h]       
  \fbox{\includegraphics[scale=0.2]{ente1}}   
  \hspace{30px}
  \fbox{\includegraphics[scale=0.2]{ente2}}
  \hspace{30px}
  \fbox{\includegraphics[scale=0.2]{ente1}}
  \captionof{figure}{this is the caption}
  \label{materialflowChart}
%  \end{figure}

  \begin{abstract}
\blindtext
  \end{abstract}
]
\blindtext
\end{document}
