Petri release a few horn buttons around the same time: the Golden (or Greek) Lady, St. Christopher and the Sun & the Moon.
St. Christopher is the patron Saint of travelers. The Sun and Moon, IMO, appears to be of some navigational meaning.
I wondered if the Greek Lady kept with that theme. Does she represent a Greek Goddess of travelers. I researched but could not locate a direct match as there is no Goddess of travelers. Rather, Hermes is thought to be the God of travelers.
Could the Golden / Greek Lady be Aphrodite, the Goddess of beauty? See attached.
I couldn't find any other goddesses (or gods) that resembled the one found on the horn button.
