This is brilliant. The reason why is that it relates to the name in a meaningful way, and is atypical of what is expected within the genre. When every uses a tow hook, then it's time to use something else. Too bad the client didn't have the vision to understand why this would have been a great approach to brand his business, to stand out, not fit in. When everyone zigs, you need to zag. Are you more likely to remember this, or remember tow hook for a tow company.
The thinking behind this shows that not only is Joe a great designer, but is also skilled in advertising, and logic behind good branding.
