[Germany, ca. 1969]. A curious "computer"-like device comprising 111 recipes printed to the blue sheets (measuring 10 × 14.5 cm, with punch-holes along all sides), a U-shaped stylus, and an index card. Also included are four blank cards with punch-holes still fresh, which can be used for additional recipes, to be added in manuscript by the owner. Housed in the original black-and-white decorative portfolio, designed in the style of the Swinging 60s. Also included is a 28 pp. booklet of instructions, affixed to the inside of the portfolio and visible through the die-cut window in which the stylus rests. Laminate starting to detach in certain places, otherwise very good or better.
Herpel's device, a kind of proto-app for which he applied for a patent in 1969, was meant to help hobby-mixologists determine which kinds of drinks to prepare for various numbers of guests based on the available kinds of spirits and other ingredients. The box contains 111 recipes (with four blank cards to which additional recipes can be added), which are sortable by 51 potential attributes using the included U-shaped stylus.
