Double Cancel Thematic

Looking at Filipo's US#26 with the double cancel made me think it would be a great theme for an ongoing thread. Not wanting to hijack his discussion, I'll start a new one here.
Show us your covers or stamps with double cancels, be they from redirecting or what have you. As long as more than one cancel, from different locations, appears on the stamp.
I'll start with a not too ancient cover, postmarked in New York NY on May 11, 1950, then again in Toronto the next day, May 12.





What you got???

No takers on the double cancel? Too much like a double negative?
Here's another with New York/ Toronto cancels overlapping, a six months earlier.





This one from Fortune Magazine.

I'm struggling to locate anything I can contribute

Hmmmm. So no takers, eh?
Ok, one more, then I'll leave it be.
Make mine a double double.

Sent from Independence, Kansas to Akron, Ohio, then rerouted to Chicago Illinois.





backstamped...





Plus a few extra auxiliary markings as well.
