YOUR PRESTIGE AND OURS.

YOU believe in your own business and
you’re proud of your product. You’ve

And the prestige of each article is the prestige
of its maker.





So it is with us of the Dunlop Rubber Co., Ltd.
We make Dunlop solid rubber tyres as we
make every other Dunlop article—as well as
we know how, and how well that is, is shown by
the overwhelming supremacy of this Company
in the tyre trade of the country.

Buy Dunlop solid rubber tyres—for you’re
buying Dunlop prestige as well.
