Exhibitions were much more fun back in the day. They were like no-holds-barred pasar malams, but held indoors in an aircon environment.
Exhibitions were held at the Sinkie World Trade Centre (now Harbourfront). One exhibition could be selling books, aquatic pets, toys, food, cosmetics, health supplements, electrical appliances, all at the same time.
Those were the days before the internet, before (or during the early stage of) the MRT. When you needed to take a ferry to Sentosa and that island hadn't yet become a tourist trap.
