One Minute Washing Machine Company Newton Iowa Wooden Plank Crate Maytag

I’ve collected vintage appliance material ( advertising items, displays, etc ) for nearly 40 years, particularly Maytag. I have never seen a piece like this before. Up for bid is a plank of wood from a shipping crate for the One Minute Washer company of Newton Iowa. The company started in 1907. I’m not sure how long this company lasted. There were several companies at this time making some variation of a wringer washer, initially wood, then various materials ( aluminum, copper, porcelain ) This plank measures 33 by 7 1/2 inches.
