Why wouldn’t it be drinkable?
They probably had cork stoppers. If the bottles were stored upright the corks will shrink as they dry out and the alcohol evaporates
You can drink it. You can also drink turpentine.

Dude, “proabition era”....meaning its bootleg uncontrolled bathtub type hooch. Even if it was drinkable when it was distilled, no telling what its turned into in the time since. LOL
I doubt a bootlegger would use industrial sealing standards when storing his booze for a short time between production and sales.
I wouldn’t chance it myself.
It could be if the bottles were tightly sealed. In 1975, I was staying at a friend's grandmother's house, when he brought out a bottle of rum to flavor our coffee. It was Bacardi, but I noticed the bottle looked different than the usual Bacardi bottles. Then I saw on the label that it was from Cuba, and the date was 1953. It was half-empty but it still tasted good.

Some distilled spirits can turn rancid tasting & cloudy over time. Particularly true with lower proofs. It’s not so much the alcohol itself, but the additives, coloring, etc.
