Very cute! The Italians called this wagon the Panoramica.
Autobianchi was a conglomeration of three Italian companies. The old Bianchi automobile company along with Fiat and Pirelli. This company was formed in 1955. The Bianchina was the company’s big hit (1957-1970.) Based on the Fiat 500, it was stylish and cute.
