Color cards and advertising literature should not include any reference by the use of words or sketches to indicate or reccamend a product for children's toys equipment furniture etc. unless it is absolutely free from toxic materials Foisonous Colors - It is generally conceded there is relatively little danger of toxic effect from paints on toys and nursery furniture as both the paint manufacturer and the toy manufacturer are familiar with the types of nous pigments to use Nevertheless the individual company should constantly guard against using any toxic material especially lead compounds in products for finishing children's toys etc.
