Since I'm the only one in our apartment who informs people I live here, I tend to be the only one who gets junk mail. The most recent one still intrigues me.

The contents were your average junk mail: "Please send us money so that you can get ripped off in return." It was for a museum, so I was more interested in normal. I kind of like museums. But it was the envelope that intrigued me the most. The stamp has no amount on it, but merely says, "USA NONPROFIT ORG." I guess it was nice of the USPS to allow nonprofit organizations to send mail for free. But the part that really got me: there's no postmark. Does the post office not find it necessary to acknowledge that these letters have gone through their hands? And it's not like someone could have slipped it into our mail slot. Our boxes are securely guarded with a lock only opened by the mailman.

So this is the part that intrigues me: Can I remove the stamp, place it on another envelope, and send it off in the mail? I hereby found my own nonprofit organization, the sole purpose of which is to send a letter for free.
