Dear Farm Bureau Patron: 
The Lake-Cook Farm Supply Company is your company and your rep¬ 
resentatives, its directors, emphatically stress that the best possible service 
that is to be offered be given to you at all times. 
A great deal of thought and care is exercised in selecting and pur¬ 
chasing the different varieties of seeds and merchandise in order to give 
you the best quality available at reasonable prices. In no case, however, is 
quality sacrificed in order to give a lower price. 
Your company, through your confidence, experiences the largest volume 
by far on seeds in 1938, which again puts it in a stronger position to obtain 
the very best qualities at lower prices, and give you this service which is 
deserving to you. 
May we again have your confidence, your patronage, your boasting, 
your suggestions, and good-will through the year, 1939? 
Yours for a successful year, 
LAKE-COOK FARM SUPPLY COMPANY.
