It's been 80 years since the Burma Shave Company erected the first Burma Shave signs along a stretch of Highway 61, here in Minnesota. The campaign grew to over 7000 signs during its 26 year life span.
From the first pretty-straight-forward, non-rhyming slogan:
Shave the modern way
Big tube 35 cents drug stores
To the last in 1963:
It's our best
Burma Shave captured the American travelers attention and whim. Consumers flooded the company with their own submissions. Songs have been written and performed about these signs.
