The children will have a vacation from 20 December through 17 January. [I] took a day off on All Souls' Day. [Missing text — you] write so little. How are you? Has the family grown? Are you all well?

A famous German circus is on tour here now with many animals and artists. They say it is very good. We are planning to see it with the children. Everyone has been excited by the so-called saucers for the past few weeks. These fast-rushing heavenly phenomena have been and still are keeping scores of scientists busy. [Name redacted] surely saw them or read about them — these amazing flyers moved at a speed of 12,000 kilometers per hour. We wish you all good health and send our regards and affection to mother and the children. Much love and many prayers, [PAGE 3] [No extractable text — image-only page]
