[Tex/LaTex] Graphics with bottom border for signature capture

Question

I am generating PDF documents using pdflatex with signature images which are pre-converted with Inkscape to pdf.

The current template looks like this ({{ tags }} are django template tags):

\noindent \begin{tabular}{l l l}
CUSTOMER: &   \includegraphics[width=6cm,height=1.5cm,keepaspectratio]{{ customer_sig2 }} & Date: {% now "SHORT_DATE_FORMAT" %}\\
                         & {{ qb_full_name|upper }}      & \\
REP:          & \includegraphics[width=6cm,height=1.5cm,keepaspectratio]{{ rep_sig2 }}  & Date:  {% now "SHORT_DATE_FORMAT" %}\\
                         & {{ qb_rep_name|upper }}
\end{tabular}

Below is rough example of what I currently have and what I need (link):

The signature images are created as PDF with Inkscape from svg base64 data. It seems Inkscape automatically crops to nearest edges. Thats called from python without many options – x = Popen(['/usr/bin/inkscape', tmpfile.name, '--export-pdf=%s' % pdf.name])

How can I best recreate the example image in latex?

EDIT:

Current signatures after help from Przemyslaw, using the following code (showing bottom and left and right margins of page):

\noindent \begin{tabular}{lc}
CUSTOMER: & \includegraphics[height=1.35cm,width=6.1cm,keepaspectratio]{{ customer_sig2 }}\\
\cline{2-2}
 & \multicolumn{1}{r}{\rule{0mm}{4mm} Date: {% now "SHORT_DATE_FORMAT" %} }
 \end{tabular}
 \hfill \begin{tabular}{lr}
 REP: & \includegraphics[height=1.35cm,width=6.5cm,keepaspectratio]{{ rep_sig2 }}\\
\cline{2-2}
& \multicolumn{1}{r}{\rule{0mm}{4mm} Date: {% now "SHORT_DATE_FORMAT" %} }
\end{tabular}

FYI – I'm using jSignature plugin to capture the signature.. THe standard box dimension is 378x95px
Example of signature being pushed down by height of image (this would have been a fixed width with keep aspect ratio, no fixed height specified, see hrule for rep signature is nudged down a bit):

Answer 1

A quick solution, with pictures changed:

\documentclass{article}

\usepackage[draft]{graphicx}
\usepackage{url}

\begin{document}

\noindent \begin{tabular}{l l l}
CUSTOMER: &   \includegraphics[width=6cm,height=1.5cm,keepaspectratio]{at} & Date: \\%{% now "SHORT_DATE_FORMAT" %}\\
                         & {\url{ qb_full_name|upper }}      & \\
\end{tabular}
\begin{tabular}{l l l}
REP:          & \includegraphics[width=6cm,height=1.5cm,keepaspectratio]{at}  & Date:  \\%{% now "SHORT_DATE_FORMAT" %}\\
                         & {\url{ qb_rep_name|upper }}
\end{tabular}

Second version:

\noindent \begin{tabular}{lc}
CUSTOMER: &   \includegraphics[width=5cm,height=1.5cm]{at}\\
\cline{2-2}
 & \multicolumn{1}{r}{ Date: 05/23/2013}
\end{tabular}
\hspace{1mm}
\begin{tabular}{l c}
REP:          & \includegraphics[width=6cm,height=1.5cm]{at}\\
\cline{2-2}
  & \multicolumn{1}{r}{\rule{0mm}{4mm} Date: 05/23/2013}
\end{tabular}


\end{document}

Two tables in one line. Package url for underline char. Frame around at.png is a picture. I have removed keepaspectratio to show the begaviour of Date: 05/23/2013, one of them with correction of depth.
