Undefined control sequence, when using font in tikz node

I get the following error when using font keyword in TikZ node

Undefined control sequence ...t=\small,black,rotate=90] at (-1/4,22/4) {

where the code is,

\node[font=\small,black,rotate=90] at (-1/4,22/4) {$W_1$};

If I remove font=\small, there is no error. What is the problem and how I should avoid it?

Edit1: Minimum Working Example,

\documentclass[class=minimal,border=0pt]{standalone}
\usepackage[utf8]{inputenc} 
\usepackage{tikz}
\usetikzlibrary{calc,3d} 
\begin{document}
\begin{tikzpicture}[scale=0.5]
    \draw[fill=brown,opacity=.8,very thin,line join=round]
         (0,0) -- (-0.5,0) -- (-0.5,11) -- (0,11) -- cycle;
    \node[font=\small,black,rotate=90] at (-1/4,22/4) {$W_1$};
\end{tikzpicture}
\end{document}

I use texlive 2012 in Ubuntu 11.10, if it makes any difference.

I don't have any problems with your code. Please add a minimal working example (MWE) that illustrates your problem. – percusse Feb 12 '13 at 14:03

Remove the class=minimal option from your documentclass options. minimal doesn't provide any font sizes, which is why font=\small causes an error. – Jake Feb 12 '13 at 14:11
@Jake: Thanks a lot! It solved the problem :) – Rasoul Feb 12 '13 at 14:13
