How do we deduce that it's from circa 1968? This is the same time frame of the 1968-1970 Central Road photos. Look at her watch - it's the small round type popular during the late 60's to early 1970s.
Observe that the slightly modern cars were using slanted parking (without parking lot lines) under the overhead power lines. Find the Volkswagen Beetle ("tortoise car"). That telephone booth was not dismantled for many years and was full of swallow poop. Spot the first roundabout in Repok Road between block 2 and 3. There's no clock tower (which was built in early 1970s) at the river front. From the shadows of the buildings, you can guess it's about 2-3pm.
Compare the cars with the antiquated cars from this 1958 picture - so the 1st picture is not from 1950s. Whatever happened to those lovely 1958 antiques after they were retired? (Update: Reader STLau emailed that the cars did not belong to Sarikei but belonged to VIP visitors to Sarikei during a big occasion)
Block 3 (right, counting from the Rejang River) of Repok Road was burned down in 1990 and a monolithic 4-storey block replaced it. This is the second biggest heritage loss after the burning of Cathay cinema block in Central Road. Luckily, the Block 3 (left, not shown) is almost an exact duplicate of Block 3 (right) but Block 3 (right) had some interesting tenants ranging from the Cantonese Association to some of the best kam pua noodle vendors in town. Do you still remember how they shout orders like "Kam pua mo neek!" (without meat in Foochow)?
