Part of the panoramic view of Middlesbrough Dock from the footbridge is clearly shown in this undated Albert Weller slide. It looks to be from the late 1960s as it shows the "yellow submarine" dock offices with which THPA replaced the previous magnificent BTDB office in Dock Street, just opposite the entrance to the footbridge.
The subject vessel is the BENARTY. See: viewtopic.php?f=57&t=8175 for other views and details.
