A rebus is a letter or letter-group that is described by a word or phrase, introducing new spacing as appropriate, such as B = abalone ("a B alone"). In the May 1973 Kickshaws, David Silverman gave two lists of single-letter rebi taken from the Enigma, the monthly publication of the National Puzzlers' League, and asked for improvements. Rather than try to invent new ones, as did Ernst Theimer in the August 1973 Kickshaws, I will simply give my own list from the Enigma; being more inclusive, it should have something to satisfy every rebic taste.
