Maskelyne and Cooke, Egyptian Hall, London
Maskelyne and Cooke Egyptian Hall programme. Someone has written on the cover of the programme the date 1875. This would be consistent with Psycho being in the programme. Psycho was introduced by Maskelyne on 13 January 1875. In the early days, Psycho only played whist, as on this programme. Later on, Psycho performed other tasks as well as whist.
