I picked up this postcard at Wirral Transport Museum recently and having tracked the same photo down in the book ‘Southport in the age of the tram’ by James Dean & Cedric Greenwood I can say that the authors say this of it:-
Company cars 16 and 11 pass on Lord Street at the junction with Eastbank Street Square about 1907-08. The book credits the photo to the Geoff Price Collection. They go on to say that the neo-Elizabethan timbered building on the right is Lomas’s (later Cannell’s) a high-class fashion store which opened in 1905
