Cusp from Stamps & Such has a question from this set of tourism stamps from 1990:

In the background of the stamps there are also four buildings but I recognised only two of them, i.e. the Sri Srinivasa Perumal Temple at Little India for Indian Dancer, and the Victoria Concert Hall for the Ballet Dancer. I thought the mosque was the Sultan Mosque, but the drawing does not matched up somehow. I am clueless about the Chinese Arch. Anyone can help?

If you know the answer, post a comment in Stamps & Such.
