This paper car is the Toyota Publica, designed by Gazoo. The Toyota Publica was a small car manufactured by the Japanese automaker Toyota from 1961 to 1978. Conceived as a family car to fulfil the requirements of the "national car concept", it was the smallest Toyota car during that period and was superseded in that role by the Toyota Starlet, which itself started out as a version of the Publica.
It was available as a 2-door vehicle only, but in a selection of body styles, ranging from the base sedan through a station wagon, convertible, coupé and even a pickup, which outlived the other models by a decade, and spawned other models, such as the Toyota Sports 800 or Toyota MiniAce.
