In the early 1960s, Seika Note Co. Ltd. of Japan began to add characters from cartoon magazines and television to its range of children’s stationery. They had already produced notepads and sketchbooks to tie in with Thunderbirds and Captain Scarlet And The Mysterons, and considering the popularity of the Anderson shows in Japan, Joe 90 merchandise naturally followed.

Illustrated left are two notepads. The first features Joe in a spacesuit with a camera, floating close by a Gemini capsule about to dock with a satellite which looks suspiciously like Thunderbird 5. The second has Joe in a flight suit in front of an aerial dogfight between Joe's fighter jet and two other planes.

The inside front cover on both notepads features monotone drawings of the Rat Trap and the cottage, the inside back cover has plan view line drawings of Mac's car, and the back cover features do-it-yourself cut-out special glasses. There are 36 blank pages to write notes on.

Seika Note also produced a Joe 90 sketchbook.
