Is this Sainsbury's newest fleet of ultra-green delivery trucks for its expanding online business? Or is it a shot of one of the retailer's so-called 'orphan stores' ahead of refurbishment? Neither, in fact - it's a vintage picture of Sainsbury's Guildford store, which celebrates its centenary this year. The store, Sainsbury's oldest still in existence, first opened its doors in November 1906. This picture was taken in 1929, in an age before 'display until' dates, reformulation programmes and signpost labelling. Sliced bread had been invented only the year before and Jamie Oliver's mum was probably just a twinkle in his grandma's eye. Funnily enough, it was also the same year the Tesco name first appeared above a shop.
