Ozo. Tonanso Kokoku-bu. Two albums with mounted examples of advertising, packaging, pamphlets, posters, stationery, etc, etc, etc, from the Tonanso Advertising Department. v.p. 1931 to 1934. Two card albums 30x23cm, lettered by hand and numbered 1 and 2; each bulging with mounted examples. 1: 35 leaves, removal from one page. 2: 89 leaves, removal from one opening and one leaf, a couple of other items with some damage, some of it purposeful, eg a piece clipped from each of the large posters. Binding pins of the first album separated by the strain of the heavy cardboard boxes. Au$3000

A wondrous collection; it even includes a full size rubbing of a carved kanban - shop sign - on drafting tissue (94x68cm). This is an education in just how much design, printing and paper engineering goes into getting your product into every home in the country. From the seals that go on packets to letterheads, to promotional postcards, through to a couple of large posters (94x62cm) and that kanban. And packets, packages, boxes ... With these albums you could have Stomachic Ozo back on the market in no time.
Tonanso was the parent company of Ozo - an ointment for every skin, every surface, malady ever suffered by humankind - and Stomachic Ozo which likewise cured every internal malady. Ozo for skin is still made, by another company. Though it now only cures a handful of skin problems, I read somewhere that it still has diehard fans despite the drawback of staining clothes. Almost needless to say: the packaging and advertising are dull dull dull.
From what I can find out, which isn't much, Ozo ointment went on the market in the mid twenties. The current makers have cut any connection with quackery in the past and give no history of their product.
