What LaTeX markup would one have to write to produce a result similar to the image below?
Please excuse my Paint-and-mouse drawing skills. 🙂

\documentclass[12pt]{article}

Thanks to input from @HKumar here's a fix that uses two xshift commands - one xshift for each of the centres of the nodes which are joined by the brace.
It still would be nice to know why one xshift doesn't move the whole brace as experimentation with the first xshift value in the \draw [decorate,decoration= below seems to have no effect.

% defining nodes at the points that are the ends of the left brace on the figure
\node[draw] (TopLeftPoint) at (0.5,5.0){box1};

%changing xshift and yshift values on next line doesn't seem to affect the brace at all
\draw [decorate,decoration={brace,amplitude=10pt},xshift=-400pt,yshift=1000pt]
([xshift=-.7cm]BottomLeftPoint.center) -- ([xshift=-.7cm]TopLeftPoint.center) node [black,midway,xshift=-0.6cm]
{\footnotesize $P_1^*$};
\draw [decorate,decoration={brace,amplitude=10pt,mirror,raise=4pt},yshift=0pt]
(3.5,0.65) -- (3.5,6.5) node [black,midway,xshift=0.8cm] {\footnotesize
