A photographer from Sibu chanced upon this blog and was kind enough to send in this picture.
Updated: Higher resolution picture posted. Find the old wharf (made of 2 sections) during the high tide (the 2 sections were almost horizontal). A ship was berthed near the customs building in the background. The old shops looked quaint but nice.
Let us do a bit of verification. You can see the clock tower which was completed in 1974. There was an interim Terminal 1 (T1) which opened on 1 Sept 1991 (updated) (click Wharf label) before the current Terminal which opened on 14 Apr 2001 (updated) . So this picture falls in the correct time frame of 1974-1991. It's always fun to do this sort of time check.
Do you recall those massive logs used by the sampans to berth? What trees were those? Find the kids walking precariously on the log. Observe the mangrove trees that used to lined our wharf. Also note that the cargo wharf between T1 and T2 had not been built yet at the location of the logs.
Finally, walk down memory lane at Bank Road and Wharf Road and say hello to the police at their station at the end of Wharf Road. They were still checking whether you had paid your bicycle fine for cycling at night with no lights.
