Five cards, five singers:  Anita Mui, Leslie Cheung, Danny Chan, Roman Tam, Wong Ka Kui — all now deceased, and commemorated on this “Postage Prepaid Picture Card Series No. 31” from 2005, with matching postage pre-printed on the reverses.  We only can show one card because of the way they were originally bound together, but if you want more information, please ask.  Grade: 1
