Found!

Because I am an inquisitive person (especially on recycling night) I stopped to look at this on my way home last night, in front of a house on my street.



Hmmm.



Very large paper bags.

On the way back from my run later I grabbed the whole bale, lugged it home, and plunked it on the table.



Holy moly, what is that design?

Weird!



And, yes, they are big (I have normal-size feet):



The world is a very interesting place.
