In the early 70's of the 20th century, the asian state of Bhutan, was world leader in emitting odd stamps.
In what follows, i'll show you 2 series of static 3D stamps. Static, because the image doesn't really move.
It gives you a 3D simulation of an object and it's background.
Although it might not be as impressive anymore as it was in the 70's, it's still a fine piece of printwork.
I wonder how Bhutani people must have experienced those stamps in those days.
The first series i show in this post, emitted in 1970, is a set of 13 wildlife animals. The set has commemorative and airmail stamps.
They're all printed on hard plastic paper. All unperforated and protected with a paper foil on the back.
After removing the paper foil, the stamp was ready to be used on an envelope.
Secondly, also from Bhutan, a set with vintage cars. Very nice, and surely wanted by theme collectors.
But that will be for a later post.
