One of my favorite logos to date. The final product after dozens of variations. The workhorse helps fire fighters fight fires. It is a division of Madison Truck Equipment. These logos went through a hundred designs to get them just right. You can also the bumper sticker for a different logo treatment.
This logo went through 12 round of designs. Below is a screenshot of my master file for the twelfth round of design. Each logo is slightly different: font, kerning, tagline, color, etc. Above you can see I've taken my favorite and created a reversed and monochrome version to make sure the logo will work in multiple media.
