Portable Road Signal (Jul, 1947)
I just like this because it looks like a skull.
Portable Road Signal
When trouble makes a stop along the highway necessary at night, this easily folded Sav-A-Life signal comes in handy. Its reflected light is visible 350 yards in either direction.
Then someone got the idea to put decent reflectors on the cars themselves.
Quite literally a bright idea…
