There is one thing in this first photo that might still be there today.

Here is South Grove, and the corner of Arkley Crescent, Walthamstow, 1969. (Image courtesy of Vestry House Museum picture archive)

Next is a 1939 view of St James Street, Walthamstow, courtesy of Vestry House Museum picture archive. The A.H.Edwards opticians shop looks fantastic. Next door, C.J.Smith is a 'commercial stationer'. Note Barclay's Bank and Sainsbury's in the background.

The same street in 2019 has plainer shop fronts, but there is still an opticians in the same premises.
