The first picture was taken in the mid to late 60s – I’ll say 1968. The corner shop was a Co-op grocery. The Co-op, the Wolverton Industrial and Provident Society, to use its proper name, was a dominant force in Wolverton shopping. About half the retailing outlets in the Square and a good number in Church Street were run by the Co-op.
You can see the houses that used to be part of Buckingham Street and the Gas Board showroom on the corner of Radcliffe Street. The old style corner lamppost has been removed but the post box (presumably the same one) maintains its place. The pram that the woman is holding, although smaller than those of the 40s, is of a type not seen nowadays.
1968 pre-dates the supermarket, although groceries like the Co-op and Dudeney and Johnston on the diagonally opposite corner were offering a larger range of foods. Food shopping was still a daily occurrence in the late 60s but the acquisition of fridges and the arrival of packaged foods meant that more could be stored at home.
