Some people collect stamps. Some people collect cancellations:

I love this. You’re not collecting a thing, not really; instead you’re collecting evidence of an act—or, maybe two acts: the physical thunk of the cancellation stamp on paper and the physical passage of the letter.

Just in case you were curious about cancellations: wow.

The source, amassblog, also has one of Paul Rand’s business cards. I keep wondering if I would think it was beautiful (I do) if it didn’t have Paul Rand’s name on it?
