One of the most beautiful Stamp Set and Souvenir sheet from China Post incorporating 4 different printing technology. A big shout out and thanks to Rohit Jain (Toronto Canada) for these stamp set. This set was sitting in my unpublished Blog holographic material box for quite some time as the holographic effect was difficult to detect initially when I first got it (thought only one stamp and the souvenir sheet had cold foil printing) but once tilted properly the effect could be seen in all the stamps. Discovered other features on the stamp and souvenir sheet while researching the stamps for 3D holographic foil printing.

The border features rare flora and fauna of Daocheng Yading Area.
The Fourth Stamp (Bottom Left Stamp) and the Stamp on the Souvenir Sheet is printed with thermochromic ink, which when heated to temperature above 45℃ the white mountains on the fourth stamps turn grey from white while the mountain on the Souvenir Sheet turn from white to blue.
