Issued in 2020, Hongkong Post’s Postage Prepaid Picture Card Series No. 62, a set of four 3D (lenticular printing) cards whose views show Victoria Harbour past and present, depending on the perspective.  These unused cards are very heavy, absolutely brilliant, and a gem for any collection.  Our scan shows the front — blurry because 3D doesn’t scan well — and typical reverse showing prepaid postage.   Limited quantities of two types of set are available:  without any stamp cancellation (Grades: 1, $33) and with special cancellation (Grades: 1, $36).
