In December 2024, Hongkong Post issued Postage Prepaid Picture Card Series No. 78, a set of three cards announcing the arrival of two adult pandas from China’s Sichuan Province to Hong Kong’s Ocean Park, where four other pandas (dad, mom, two babies) were already in residence.   If unused, these cards had pre-paid postage good for airmail delivery worldwide.   We have three sets, each with a different first-day-of-issue cancellation:  GPO, Philatelic, or Special.  Our scan shows the front and special Philatelic postmark for one of those sets.  Your choice.  Grade: 1
