SERVICE 
ilrtHAT service do you require of your printer ? Do you 
Vl>/ require assistance in writing copy ? Do you require 
proof-reading service that corrects not only the mistakes in 
the proof, but errors in the copy as well ? Do you occa¬ 
sionally require unusually quick delivery ? Do you wish 
to have your printer store your printed matter and ship it 
on requisition ? Such service we have been giving our cus¬ 
tomers for years — and we are proud of the fact that they con¬ 
sider this service as a matter of our daily performance.
