In the 1970′s Peter Tietjen was working at PAN (at the same time as Ken Hatherley) and he came up with a design for a “self-erecting piece of display material that was going to completely revolutionise in-store book displays”
I found the following on an Australian website;
DISPLAY UNIT – 198704242
Owner: Pan Books Ltd Designers: Peter Tietjen Description: DISPLAY UNIT Statement: Monopoly is claimed in the shape and/or configuration of a display unit as illustrated in the accompanying representations. This page contains all relevant details related to design number 198704242. This design was lodged on 18/11/1987 and has a status of Currently Not Renewed. The owner of the design is registered as Pan Books Ltd They used the attorney firm Griffith Hack to file this. The design was registered on 15/12/1988 and has been renewed to 18/11/1993
I’ve tried to contact Peter but no luck so far. Does anyone know if it actually “revolutionised” displays as we know them?
