The problem I have with novelty signs like that is I'm space limited. I have to take advantage of the space I have to store tools and spare parts. Plus, I've never figured out a way to display cool signs like that without looking like a hoarder.
A bit messy with our Jeep's soft top stored in my office. Now that you mention it, it does kind of resemble a hoarder's stash. Definitely need some new pics after a tidying up.
