If you don't look closer and carefully, it is not easy to spot the differences before 2 'Plan of Ports' both issued by the Port of London Authority.
There are several obvious differences between 2 plans:
1] Font types: 1964 plan is more neat but the 1934 plan seemed to be hand-drawn
2] Indications of location: 1964 plan has more clear indications
3] Extra information: 1964 plan no doubt have much more details and figures than the 1934
On 1934 plan the underground station nearby the Tower of London was still called 'Mark Lane Station'. But on 1964 plan it was renamed to 'Tower Hill Station'.
On 1934 plan the Export Dock was still in the East India Docks but it disappeared on the 1964 plan.
the docks in the Royal Victoria Dock (A to I) were gone and the right-hand side of the Pontoon Dock was filled as well on 1964 plan.
image from the 1964 plan shows the Royal Victoria, Royal Albert and King George V Docks, taken by the Aerofilms.
