Art Deco Whistle mistake?

[Timelypicken]

The top of the soda is unlike any other whistle sodas I’ve seen. Was this a mistake, uncommon, or something common they did and Im just dumb?

It's a PRIOF crown. Supposedly did not require a bottle cap opener. It probably has PRIOF embossing around the lip. Not widely used I have a couple of embossed beer bottles with this type of lip.

I have this big boy with a PRIOF top, i always thought it was pretty neat. Anyone know if this one is uncommon?
