New Year's greeting card 1940, featuring drawings of sailors.

An advertisement agit-prop for using superphosphate and nitrogen-based lime fertilizer in agriculture. Father Brázda has sown and his friends - the artificial fertilizers - help him reap a rich harvest. We can illustratively watch how they take care of the sown plants, provide them with nutrition and fight the weeds to make the grain strong and increase its yield. Another farmer, experiencing a low harvest in an agricultural cooperative, wonders how Brázda could achieve such great farming results.

A commercial promoting artificial fertilizers. Two neighbours, Moc and Malý [Power and Small], grow potatoes, but their yields are different. The one who only fertilizes his field with manure crops has very tiny potatoes but the potatoes of his neighbour - who uses potash for growing - are beautiful and huge.
