The Larssons are poor. They have so many children there's scarcely room to turn around in their tiny apartment, let alone sleep. When their father's rich half-brother dies and leaves them only two draft horses and drays, Mrs. Larsson comes up with a novel idea - Mr. Larsson, who is an inventor when he's not a traveling salesman, will turn the wagons into caravans and they will spend the summer touring the countryside. Where does the Peep come in? Well, Mr. Larsson has designed a marvelous saucepan, and they will finance their journey by selling it along the way.
It's a wonderful summer. They meet a down-on-his-luck hot dog man, an eccentric old woman, a man who might be a murderer. They discover thieves, wonderful lakes, and fascinating Swedish towns.
Bring it back? Absolutely. Even if you're not fascinated by Scandinavian children's literature, as am I, this is a wonderfully nostalgic summer read. While it lacks racial diversity, not surprising for the time period and location, it portrays a family that is poor in economic resources but rich in imagination, ingenuity, and love. The original illustrations are colorful and appealing and it's a strong family story that will appeal to readers who like this type of lazy summer reads.
Availability? It's fairly common in smaller libraries - worldcat lists multiple holdings. Used copies also proliferate online for a reasonable price. Unfortunately, it was last reprinted in the 60s so you're unlikely to find a shiny new copy that will stand out on the shelf.
