Currency Stamps of Singapore

The currency stamps of Malaysia released early of this year are just not appealing to eyes for some reason. I looked through my stamp album and I found this block-of-4 currency stamps of Singapre sitting at one corner of the album. These beautiful stamps were issued on October 2, 1992. They are so appealing eventhough the shape of the stamps is square (not round). To be honest, this set of Singapore currency stamps is actually one of my favourite stamp sets!
