inspired by recent e-mails, I've been scouting through Life photos and this one intrigued me. Curious to know what those stencils with the triangles on the ends were for. The top one seems a different shade than the lower, yet it doesn't look like a patched re-painted mark. Why the triangles? And while I am at it, what car is this?
