This conference paper explores ghost signs: the faded adverts for brands, organisations and services that we see inked or carved on walls or above shops. I discuss: 1. the liminality of ghosts and ghosts signs – and the ways we materially engage with them 2. how they flex time and, in doing so, gift us an organisational warning 3. and how, as memento mori, their ancestors – the medieval macabre art of the three living and the three dead – ambiguously suggest not only organisational decay and dissolution but also possible continuity Finally, I explore how this continuity may involve a vampiric relationship between new businesses and the old – and the possibility of organisational resurrection.
