I started with US Navy because a friend/collector asked me for a maximum card with an American aircraft carrier, for the NATO section of his international philatelic exhibit: Fight Against Terrorism.
Eventually, I have affixed the stamp on the picture side, and I have applied on the glossy frontside my postmark that you can see, much more visible, on the backside.
In time, I will create similar Zazzle stamps with US Army, US Air Force, etc.
They all deserve our sincere Thank you!, and much more than that.
How many of us, civilians, would risk our lives and livelihood to go to war?

In general, you will go either to my photobucket album to see more, or to my store(s) - delcampe or zazzle.
In case you are really interested, you can buy what you want. If you only want to look around, you're welcome, as well. :)
