SingPost is welcoming the Year of the Ox with their set of OX-picious Zodiac Stamp (auspicious!) with 2 x free hongbao packets. Similar to the previous Rat stamp release, there is a 'double' image of the other two immediate Chinese Zodiac signs in the Ox stamps, one of the Rat (the animal before the Ox) and one of the Tiger (the animal after the Ox). Take a look at the news release from SingPost about this issue, which also contains other details like prices, denominations of the stamps ...etc.
Here's a picture of the stamps and the hongbaos. I think the hongbaos giveaway is a smart idea of promoting the stamps.
