"Do Not Pass"
"On a Slope"
"Without a"
"Periscope"
"Burma Shave"
As seen on the Pear Blossom Road near Los Angles in my youth.
Here's one I found but never saw personnaly. Enjoy.
Every Friday night, at the main gate of Walter Reed Army Medical Center in DC, when the Freepers gather to prevent the anti-troop goons from affecting our soldiers and their families, you will see this Burma Shave sign warning people about the deceptive practices of the moonbats:
“Don’t Be Fooled”
“By their flags”
“Up Ahead”
“Pinko Hags.”
