De Ferranti's Arts and Crafts style ruby lustre animal tiles are replicas of William de Morgan's decorative tiles.

The animal images were all de Morgan's own design, partly inspired by medieval manuscripts and partly from his own imagination, whereas the flower designs he would have copied from Arts and Crafts designer William Morris .

The lustre technique was widely used in Islamic pottery and reinvented for ceramic tiles by de Morgan. The lustres have a shimmering iridescent, metallic surface.
