1930s vintage pharmacy bottles, Squibb green and black bakelite lids art deco glass bottle lot

Lot of three vintage glass bottles with the original Squibb lids, green (plastic?) caps on black bakelite screw lids. I don't know what sort of pharmacy product or medicine these once held? They're about 4" tall overall.

One of the bottles is marked with the design patent number on the bottom, 91080 (dates this to 1933). All three bottles are on very good condition, no chips to the glass bottles or the lids.
