I've been reading the old books in the Electronic Library at USPCS.org. It's great that they've made these available, most are very expensive.
As I was paging through all the fancy cancels in Cole's "Cancellations and Killers of the Banknote Era" I noticed one called the broken heart (HE-26 - HE-29), and it made me think of this stamp. It's not pretty, but not just an ink smudge, so I've always been a little curious as to what it is. Is this some postmasters attempt to copy the broken heart cancel? Probably a stretch, but it looks like it's supposed to be SOMETHING.

I'm also curious about the cancel on this postcard. What is that little killer right on the edge of the stamp? It also looks like it's supposed to be something, but maybe it's just a partial imprint.
