Singapore Tourism Low Value Definitions -1990

Bought a set of  9 stamps of Ebay that were from 1990.  They are basically low value tourism definitions.  Sorry that the scanned picture did not come out well and the colors are not really depicted correctly.  Need to get my scanner to work properly.

The stamps depicted are as follows:
5 cents - Singapore Zoological Gardens
15 cents - Sentosa
20 cents - Singapore River
25 cents - Dragon Boat Festival
30 cents - Raffles Hotel
35 cents - Bird Singing/Watching
40 cents - Jurong BirdPark
50 cents - Boat Float
75 cents - Peranakan Place
