He discovered by accident an idea
that has saved the strength of millions
In a printing office in Lynn, Massachusetts, 25 years age
worked a ticca txjiiipuwter.
All day long lie steed in front of his case setting' type.
Net die hardest work, perhaps fiat lie fband himself each
nigfit with little energy left: and generally a backache in
thebargwn!
One night he tea unaccountably fresh after werlr with
fats backache gene. Fer several days this kept up
Suddenly the expTariatieg. dawned en. him. These days
instead of standing en the hard fleer he had steed en a
robber mat he had found about the office
Leng before ear morning newspapers

the seismographs in New Yerk Gtj bad

The shocks and jars from dry trecka
and streetcars which keep ear sidewalks
trembling would seen destroy a seismo
graph. Te avoid them and protect his
instrument, the scientist houses it in a
cellar, deep underground.
Is it any wonder that the human body,
the most delicate instrument of alL needs
some simple protection against constant
shocks and vibrations ?

Next morning his robber mat was gene. It was under the
desk of a brother printer. He dragged it out, cot two pieces
of robber from the mat and fastened them te the heels of
his shoes. And that was the start of the idea that resulted in
O'Sullivan's Heels.
Making a geed idea better
The printer saw the possibilities of hs discovery. And he saw that tfi
special development of a certain type of robber something far different
from hi crude rubber mat would make this idea, a fhnrmanH times mere
valuable.
Fer years he worked. Countless tests --experiments and the brains of
some of the world's best rubber experts brought it te perfection. And te
day the O'SuIlivan idea has spread throughout the country.
Loek at your heels!
Like all things of value, O'SuIlivan 's Heels have been widely imitated.
Are yours O'SuIlivan's ?
If they're net ask your repairman for e0'SuIvanV, next time! They
usually cost you no mere than ordinary rubber heels. But notice the dif
ference at the end of each day I See hew rmrrh freer you are from tired
new and strain.
You'll understand then why nuTCens of men and women today don't Just
