But with a little bit of research, you can still find lots of great stamps for your collection.
In this second post, some more holograms:
First item is a sheet from Finland.
The sheet has 3 stamps and a hologram.
Infact the hologram itself isn't a stamp, but if the sheet was used completely on a letter, it can be found as an postally used philatelic item.
What's more special albout this sheet, is that it is cut like a "tangram" a game with 7 geometric shapes, put together as a square. Each of the single shapes can be formed by putting the other shapes in a certain order.
Also other forms can be made by putting each piece in another place.
A nice game and major brain-breaker.

In this set, dedicated to scientific discoveries, several stamps were decorated with holograms.

Science doesn't have to be boring as you see...
