This photo is labelled Bishopsgate Street. The shop R. N. Wallis and to me seems to be no 77. There is a Robert N, Wallis grocer in Bishopsgate Street pre WW1, who disappears by 1921. However be is at no 14 Bishopsgate St. In the period immediately prior to WW1 he has several shops, including one at 77 Holloway Head. I think it likley that the shop is Holloway Head
