In 1865, William Booth founded an Evangelical Christian movement in the East End of London. Originally known as the Christian Revival Association, it was renamed in 1870 to become the East London Christian Mission, subsequently shortened to the Christian Mission. The group was reorganised and renamed in 1878 to become the Salvation Army — affectionately known as the "Sally Ann".
There is no way you can missed this sign on the corner of Whitecross Street and Old Street.
On the advertisement you can read: "The Salvation Army Hostel for Working Men" . Its bottom section is trickier to decipher, but seems to say 'cheap bed and board'.
One more for the collection :-) !!!
