During my younger days, i used to be a passive stamp collectors but not now...
Now, Stamps is just one of my inspiration sources.
One area of design which I think is definitely underrated is Postage STAMP design.
I have always wondered about the process behind creating these tiny designs that cross borders and showcase a countries heritage to the world. I definitely prefer the odd shaped stamps
like the circular stamps and triangular stamps. If you want to see numerous stamp designs
just type "postage stamps" into google images.
