The Late Great FO:D ranger
After reading the history of the truck and how you wish to memorialize it, I immediately thought of the Hatch Show print style. The letterpress show poster style really fit all the criteria: has a vintage feel (for an old truck), good way to display graphical elements with heavy type elements (so we can add in all the fun details of the truck), and works well with limited color.
One of the first things you may notice is the only colors are the navy and sky blue from the truck (background is the sky blue, just a lighter tint. white would be the paper color). I wanted get all the relevant facts about FO:D on the poster to properly immortalize em, one of my favorites is knowing the final odometer reading. All the type (except the ford script) was collected from authentic Hamilton Wood Type scans.
