The Emblem of Quality” 
SEEDS 
Keystone Seeds represent a standard of quality achieved through years of careful 
field testing and selecting the finest strains available in each variety. They are the result 
of careful breeding, supervised production, careful harvesting and cleaning, and their 
quality is proved by both laboratory and field tests. 
CAREFUL BREEDING 
BEAN INCREASE PLOTS ON OUR IDAHO BREEDING FARM—Every plant in these plots is inspected 
individually. 
SUPERVISED PRODUCTION 
INSPECTING ONE OF OUR IDAHO SEED BEAN FIELDS—Every field of our 
Keystone Garden Beans is periodically inspected throughout the growing season to keep 
careful check on every phase of its growth and purity from planting to threshing.
