Abstract: A device for creating an optical illusion and for concealing an object, animal or the like to be produced defines, a space in which a reflective member is transversely disposed to divide the space into two compartments. In the device the optical illusion is effected in the first or lower compartment by a lined design on the inner walls of the compartment and the operative association of the coated peripheral edges of the reflective device which blend into and form part of the design to create the effect of double the space represented by the first or lower compartment. The second or upper compartment is concealed behind the reflective device and will hold the object, animal or the like to be produced.
