We’ll try to describe this so you get the full picture, so to speak.  It’s a set of six unused cards with artwork by different persons, issued by Correios de Macau in 2016.  The set’s official reference is BPD 0106-0111.  Macao Post describes it as:  “a set of six postcards entitled “Macao Cultural Heritage – another look”, marking the 25th Anniversary of the “Macao Association of Relatives in Charge of the Mentally Disabled”. The initiative aims to obtain greater social recognition of the creativity of authors with this type of disability, through their drawings on the World Heritage of Macau.”  Everything is enclosed in a wrap, and our scan shows one unfolded side.  Those thumbnails represent the six cards, and the larger drawing (minus the Chinese characters) is similar to one of the cards.  The back of the wrap has longer descriptions in Chinese and Portuguese.  Grade: 1
