Have no idea of the designer but able to extract some info. on the hallmark, which is not clear on my pictures. H & S - O - Lion - Leopard. Not too sure of the exact date of this perfume bottle but believe it to be made in the 1900,s and is cut glass crystal - London Assay Office. any further info. or corrections would be of great help. Overall height - 7 inches and the base is completely flat/polished :rah:
