One of my favorite Christmas books for children, this is part of Elsa Beskow's Peter and Lotta series, written in the early part of the century and only recently reprinted in the USA in English. Ursula's favorite part - and mine too - is the appearance of the Christmas Goat (see the pic!), which is the Swedish equivalent of Santa Claus, but far more interesting!
"Elsa Beskow (1874-1953) is the most popular children's illustrator in Sweden, where her picture books have been known and loved for over a century."
