A beautiful red head in a pinup pose. Perhaps a WW2 pinup? GIs loved pinups and sometimes would paint them on their jeeps and other vehicles.
As you can see there isn’t much room for anything large but a skilled artist could easily paint a small picture on the windshield under the window.
People talk about Hummers and such but I say who cares. There’s nothing better than a jeep. A Ford GPW jeep is even better!
