I stumbled upon the original patent documents for a "Game Footbag",
invented by Mr. Stalberger.

Interestingly, the first invention that John Stalberger filed with the United
States Patent and Trademark Office was not a bag, but rather some sort
of disc:

Game Footbag (1974)

3 years later, in 1977, Stalberger filed the invention that was later known as the "Hacky
Sack", the classic two-panel dogbone pattern footbag:

Game Footbag (1977)

I really dig Fig. 8 in the Drawings.

Is that the pattern for the original footbag?

love the abstract. next time someone asks you what footbag is, you should say "the cover consists of two dogbone-shaped pieces of flexible material joined at their peripheries so as to form a collapsible ball. the fluid material includes a large plurality of small polyethylene particles having low resilience."

calling a bunch of poly pellets a 'large plurality' cracks me up
