Bert Allerton's “The Aspirin Box” (originally titled “Spirit Cartography”) is a later variation of the Spirit Photography Card Trick and Photographic Coins. It was first published in Bert Allerton's The Close-up Magician by Robert Parrish, 1958, p. 62. Allerton developed the trick with the help of Fred Braue in 1940 or early 1941, as documented by Braue in Hugard's Magic Monthly, Vol. 18 No. 12, August 1961, p. 139.
