This package is not only bigger than a breadbox but as high as my four drawer high Cushman dresser.
The doll shipper was housed in a box that resembled a coffin or a vault more than a typical Uline.
This big shipper on the left houses the doll of question next to an Agnes Dreary shipper.
Here is a typical full size bed.
Here is the same bed with doll box and shipper covering 2/3s of the comforter.
One can say huge things are happening here.
