The magician fills out a grid on a small card; every row, column and diagonal adds up to the spectator’s chosen number ala the classic magic square. This particular set was printed for J. Elder Blackledge, noted magician and radio presenter based in Indianapolis. A facsimile of his signature appears on the back of each card. An unusual novelty/giveaway we have not previously encountered. Includes 48 unused cards. A few cards have small stains, else in very good condition.
