was the prototype Buster really a prototype?

I don’t have a construction crew hit toy-era blister pack handy, but doesn’t that style bulge out on both sides? If so, is it possible that the blister pack in the worthpoint listing is actually opened, because the cardboard appears to lay flat against the tan cloth? And if that’s the case, could it be possible that buster was then altered? I know that is quite cynical of me, and assuming my recollection of the bulging blister pack is even correct, it would seem to require a fair amount work from the person who listed it.

Just a thought.
