I received this from a philatelic friend in Lumut. When I first got it, I did not realise this 2007 miniature sheet from Hong Kong celebrating the 10th anniversary of the Hong Kong Special Administrative Region in China (the British left Hong Kong in 1997) is actually a hologram miniature sheet. The scanned sheet does not do it justice. The 1997 transforms to 2007 and there are lots of fireworks visible as well. This is worth some US$6 on ebay. Thanks Hung!
