This is a set of six different 3D cards, printed on exceptionally heavy stock.   What you see in the photo is one card, and one sample reverse:  each card has pre-printed postage.  We have several different sets.  Two sets have the postmark you see in the scan (Grades: 1, US$34).  Two sets have a different “GPO” postmark (Grades: 1, US$34).  Two sets have no postmark (Grades: 1, US$29).
