Twice Cancelled Oconomowoc, WI Scout Camp Postcard

64 years ago I sent this postcard home from the Indian Mound Reservation Boy Scout camp. The US Sc. 1145 stamp on the address side is nicely cancelled July 20, 1960 at 2:30PM. There's a second cancel on the photo side of the postcard Oconomowoc, WI July 20, 1960 but at 1:30PM. I don't remember whether the camp had it's own little postal station to provide the first cancel on the stamp. But then why the machine cancel on the opposite side? And why the time difference? Or is the time difference just some clerk who can't tell time? Any ideas on what might have happened? I'm glad someone took the time to get the cancel pretty well centered on the stamp. And I'm glad the other cancel was run through so as not to destroy the first cancel.

The cancel times are correct. Your stamp was not placed in a standard corner to get a machine cancel at 1:30 pm which indeed was the first cancel (and mis-faced as it really should be in the normal position). Shortly thereafter, the clerk was sorting the stack of cancelled mail for in town, out of town, etc., came across your card, turned it over and cancelled the stamp at 2:30pm as a "skip". These would have been applied at the town's PO. The camp likely had no more than an informal mail collection point and a small stash of stamps to sell as a petty cash operation to the scouts as a convenience.

Thanks John. That scenario never crossed my mind.

So yes, misfaced, then caught during the first sorting and the stamp canceled with the most convenient device. All before the era of tagging, manually faced, run through a single-head machine, then sorted and pitched into pigeon holes a number of times until it got to its destination, etc.

Perhaps a more common reason to see two close-timed cancels from the origin town is a machine misfeed. Here both are at 9:30pm:

I am your same time period with scouts in WI. The important thing is that you had fun--yes.
