This is the "Hélène" perfume bottle (often classified as a flacon or scent bottle), officially documented in the René Lalique catalogue as Model No. 522.
It was designed and introduced circa 1928, placing it right in the heart of the Art Deco movement.
The bottle utilizes a highly dimensional lotus flower motif. The lower vessel forms the unfolding petals of the blossom, while the textured, domed stopper acts as the center bud of the flower.
t is crafted from Lalique's signature molded frosted glass.
The signature on the base is the key to its prestige. After René Lalique died in 1945, his son Marc took over the glassworks and dropped the "R." from the company's hallmark, transitioning the signature to simply "Lalique France." The "R. Lalique" mark on the bottom of the bottle is the primary indicator of a pre-war piece manufactured under René's personal supervision.
