A fanciful title for an official set of five unused cards, Postage Paid Picture Card Series No. 81 from Hongkong Post.  Issued in May 2025, we have two sets.  One (as you can see in the scan) has a special postmark over the pre-printed postage.  The other set has the postage but no postmark.  Each set (the price is for one) comes sealed in its original Cello-wrap.  Grade: 1
