The Ship series, of which this is part, was introduced progressively from 1984 and represented Singapore's first domestically themed definitive issue after the Orchid and Bird series. De La Rue printed the entire Ship series, a relationship stretching back to Singapore's earliest independent currency, and their intaglio work on the high denominations is notably fine — the S$500 and S$1000 notes received the most elaborate treatment, reflecting the denominations' role in interbank settlement rather than everyday commerce.
By the late 1980s, Singapore's MAS was already studying replacement security features; this 1988 issue predates the introduction of more sophisticated foil elements that would appear in successor series. The security thread here is a plain embedded type.
