Set of 5 Art Deco cut crystal shot glasses - hexagonal shooter 1920 Baccarat?

This magnificent series of 5 art deco shot glasses is made of crystal. These old shooters are entirely cut with sides and facets. Its original hexagonal shape, short on foot and flared is typical of the 1920s. It is made of solid and heavy crystal, of magnificent transparency. It is an art deco model of a lorraine crystal factory baccarat or lalique. Unsigned, it dates from the 1920s and measures 6cm high and 6.5cm in diameter. I report splinters on two glasses at the drink and on the base.
