What could possibly be inside an Amazon box THIS big?!

SEATTLE -- Monday was expected to be the biggest shipping day of the year.

We didn't take that literally -- until today.

Q13 News producer Lauren Padgett snapped this photo of a giant box with the famous Amazon smile logo on the side. The box was on a flatbed truck on Westlake Ave N near Valley Street in Seattle.



"What do you think it is?! It's smaller than a car, bigger than a bookshelf," asked Lauren.

We've reached out to Amazon to ask what could possibly be inside a box that gigantic.
