I remember seeing these in places like US 40 around Columbus, Ohio when I was a kid. They've mostly been stolen by now. The best place to see a
Burma-Shave sign is on the wall of a restaurant.
My favorite is
IN THIS VALE
OF TEARS AND SIN
YOUR HEAD GROWS BALD
BUT NOT YOUR CHIN
BURMA-SHAVE
Frank Rowsome, Jr. has collected "Texts of All Burma-Shave Signs" in an appendix to his book
The Verse By the Side of the Road,
The Stephen Greene Press / Pelham Books, Brattleboro, Vermont,
1990 -- 25th Anniversary edition
with a foreword by Bob Dole, ISBN 0-8289-0810-9
The version of the above quoted by Rowsome is
WITHIN THIS VALE
OF TOIL
AND SIN
YOUR HEAD GROWS BALD
BUT NOT YOUR CHIN -- USE
BURMA-SHAVE
He says, "Variant forms of a number of jingles occurred when they were subsequently re-used.
The commonest change was to revise the division of words among signs,
but
textual revision was not unknown", so I don't need to revise my memory!
