The current Hong Kong local postage stamp is one of the most beautiful I’ve seen. For just $1.40 (20 US cents) you can have a tiny work of art, suitable for framing. The great thing is that if you send it to somebody as a present, it pays for its own postage. It’s the gift that sends itself.
It’s also one of the biggest stamps I’ve seen – you’d be hard-pressed to fit it on a small postcard. While I was poking around in my files, I also found this fun stamp.
It’s a $1 stamp from New Zealand about 10 years ago. Very nifty, though it’s a bit fiddly to tear along the perforations. Good for sending circulars.
