rk at the station has recently uncovered these amazing advertising posters in non-public areas and that date from c1956 - 1959 when the station's lifts were removed and replaced by escalators. These are in an old lift passageway.
This striking image is for the coach services of the Royal Blue operator - who in those days were the coaching arm of the old Tilling bus companies of Western National and Southern National that by this date were state owned. they ran a network of coaches from London Victoria Coach station to the South West of England. The poster is by the poster artist Daphne Padden.
We will be leaving these intact - and please do not pester the station staff as the posters are wholly inaccessible - which is why they've probably survived 50 odd years!
The photos were taken officially - please do credit London Underground in any links.
