I’ve finally got my hands on Own Label by Jonny Trunk, a look at the work of Sainsbury’s in-house design studio from the sixties and seventies. And it’s just lovely. There’s a lot of incredible design in there – and on the rather impressive Sainsbury’s Archive site – but it’s the typography-and-geometry stuff that really grabs me. The shelf-stacking, trolley-shepherding me from twenty-five years ago would find this fascination very strange indeed.
