Note - 'Osborne Ivorex' is not 'Bossons Ivorex'. Some of the more popular 'Osborne Ivorex' pieces were re-coloured and re-framed by Bossons making them more striking. These became the 'Bossons Ivorex' range. There is an equivalent 'Osborne Ivorex' plaque for the majority of the 'Bossons Ivorex' range

'Bossons Ivorex' produced approx 50 different plaques all being based on 'Osborne Ivorex' designs.
