A conceptual sketch by Tjebbe van Tijen detailing the logistical framework for an urban performance piece titled Walkie Talkie.

This work by Dutch artist Tjebbe van Tijen documents a conceptual performance or urban intervention titled Walkie Talkie. Executed on standard grid paper, the piece functions as a preparatory record or manifesto for a four-hour stroll through a European capital. The composition combines a photographic collage element, showing a group of figures obscured by a dark, text-heavy banner, with hand-drawn graphite annotations.

Van Tijen outlines the technical requirements for the event, listing ten ear telephones, three microphones, ten drinking tubes, and ten smoke tubes. A schematic drawing of a human profile wearing a headset provides a visual anchor for the proposed communication apparatus. The text, written in English, describes the event as a stroll featuring unusual activities. The inclusion of the phrase 'op de 10 mensen roken' (on the 10 people smoking) suggests a specific, perhaps provocative, social element to the performance.

As a practitioner of conceptual art, van Tijen often used documentation as a primary medium. This sketch captures the intersection of performance art, social experiment, and technical planning common in the late twentieth-century avant-garde. The grid paper background reinforces the clinical, almost bureaucratic nature of the planning process, contrasting with the spontaneous and participatory nature of the proposed walk. The work provides insight into the artist's process of translating abstract social concepts into actionable, physical instructions. It remains a record of an ephemeral event, preserving the intent and logistical framework of a project that sought to engage with the urban environment through collective sensory experience.
