So, let's compare Lamson's experiment with the real thing.

Note first that the forward pitch of Lamson's cardboard is much more pronounced and visible than any such pitch in the real bag.

I measured, and Lamsons' bottom width is exactly 75% of his top width.

But, the real bag has a differential of 55%. That is, the bottom width is only 55% of the top width. And that's with much less forward pitch- if any.

And finally, and most importantly, the eyes can "process" Lamson's object fine; there is no tendency to think that the object is anything but oblong.

But, the real bag has a degree of tapering that exceeds what the eyes and mind are willing to accept on the same basis. In other words: on the left, we know it's a rectangle, despite everything. But, on the right, it looks like an inverted pyramid.  That bag WAS pyramidal shaped. Lamson's experiment confirms it.
