Odd stamps : 08 Stamps with special cuts - 05 b

It's been a while since I started my topic on odd shaped stamps.
I didn't realise that I only had one article on pentagonal stamps so far.
So, time for a small update...

In 2000, US post emitted a sheet with 5 pentagonal stamps dedicated to the exporation of the solar system.
The sheet indeed shows us several planets, with Saturn and a/the Moon as background and 5 pentagonal stamps forming a bigger pentagon.

3 of the 5 stamps are pictures of the Sun, it's centre and the eruptions on the sun's surface.
The other 2 stamps are depicting the Earth, seen from space and the sky, seen from Earth.

When flipping the sheet, you can clearly see the 5 pentagons, placed in a way that shaped formed in the middle is an upside down pentagon.
The whole images of 5 stamps, forms another, bigger pentagon again.
