Abstract

1,020,887. Educational appliances. W. J. GAGE Ltd. Nov. 10, 1964 [Dec. 21, 1963], No. 45838/64. Heading G5G. An educational device comprises a paper sheet with at least one visual problem 2 imposed thereon, an answer 4 imposed on the sheet in a first colour over which is superimposed a mask 5 in a second colour complementary to the first colour to substantially obscure the answer, and a transparent filter 7 in the second colour which when held over the answer and mask obscures the mask and accentuates the answer. The sheets may be formed into a book and a pocket fitted on the outside to hold the filter. The complementary colours used may be red and green or blue and orange.
