Lovely clear picture of the 58 on its way to the Blackwall Tunnel. Thanks!
I also happen to have a copy of "Round & About London by Tram, by Charles G. Harper, Vol II South of the Thames, 2nd edition.
Published by Ed. J. Burrow & Co Ltd and
"Authorized by the London County Council" (who of course ran the tram system).
Published probably late 1920's, early 30s.
Lots of adverts including those for lounge suits from 50 shillings (i.e. £2.50) from "London's Leading Tailors" in Old Street EC2.
For 1/- (one shilling) one could "ride-at-will" all day on the trams...and "see the great Metropolis in all its infinite variety and moods".
And there is a map of the All-night Cars, just like the current Night Buses, the "services that never cease".
