When I was little I used to be really into stamp collecting*. That past-time has faded away but I still love stamps as objects, they really are little works of art. They can be so colorful and funny, and interesting, and even perplexing. Of course my favorite are the older gummed ones, I hate the new sticky kind. When I was last at my family home I grabbed an envelope full to sort though, they ended up being from Czechoslovakia, these are a handful of the best ones.
*To the point where I started a Stamp Collecting Club with some girls from my Girl Scout troupe, which looking back makes me wish I was as cool now as I was then.
