Here are the images from the Pos Malaysia poster for the Primates of Malaysia Series 2.
The RM 3 Miniature Sheet is only available to SODA members (10,000 printed quantity). The RM 6 Miniature Sheet features fluorescent ink printing (something that special effect miniature sheet collectors might want to know). There are 30,000 MS printed for the RM 6 type.
