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.

Probably 1881. Jenness says in his Egyptian Hall book that on 27 January 1881 Maskelyne announced that there would be no evening performances on Mondays, Wednesdays and Fridays, which is consistent with the details in this programme.
