The text says it all:
SEMBAWANG PUBLIC LIBRARY
You can look forward to a welcoming and inviting space for all users...
Users will enjoy a spacious, open and welcoming library, inspired by Sembawang's shipyard heritage.
Well...you know what they say about Sembawang in the Wikipedia: "the Sembawang area in the early twentieth century was the site of the Nee Soon Rubber estate. During the colonial times, Sembawang was home to a major British naval base, its construction of which began in 1928 and was completed in 1938. The base included dockyards, wharves and workshops, as well as supporting administrative, residential and commercial areas. The Naval Base has since been handed over to the Singapore government, which in 1968 converted it into a commercial dockyard (as Sembawang Shipyard, now part of Singapore Exchange-listed SembCorp Marine) that went on to become Sembawang Corporation, a major state-owned industrial conglomerate."
Heh. I like the subtle use of the shipyard's photos as the watermark images in the poster. Which shipyard, you may ask. Well
The poster above is part of the relocation of Sembawang Public Library from the Sun Plaza 3rd level to the 5th level.
