So many artifacts evocative of the 1960s and 70s turn out to hail from antiquity, but the corner-shop-and-petrol-station-oriented phenomenon of Green Shield stamps only started up in 1958, despite the venerable glue-backed perforated dividend tokens looking like they hailed from some Edwardian printing press. This was, of course, partly the point. The resolutely old-fashioned ethos of saving up ‘points’, symbolised by each small stamp spewed out by a little metal machine by the side of the till and diligently stuck into a special booklet (there were bigger ones that counted for ten points or more, to save on your saliva) preached hard graft and patience. But then, when enough had been accumulated, it was off to the catalogue for – yippee! – toasters, glassware, Kenwood Chefettes and even, should you fill a comically enormous stack of booklets, a colour telly! Its was consumerism gone mad, though it worked, its only serious rival being the pale blue Co-op Dividend stamps scheme. Whatever the colour, mile-long reams of perforated paper being awkwardly stuffed into bulging purses were one of the all-time most evocative signifiers of grocery shopping.
