This feke is a diagonally cut index corner of a card joined at the two outer edges to a similarly shaped piece to make a pocket, so that the corner can be fitted over the index corner of a normal card to make it appear as a different card in a fan. The feke is used in a similar manner to a split-index card, but palming away the corner-pocket leaves the card examinable. This feke was first described by (Shaun) Yelma in Tricks of To-day, 1914, p. 46, and is claimed an original idea.
