Identification Office is a peculiar atlas of different types, sets and subsets of male and female moustache, together with short psychological characterisation of people having a given type of moustache. Below each drawing, the artist indicates the percentage of policemen and criminals boasting a given type of moustache. By meticulously analysing the moustaches and the statistical data, Moskowczenko creates a parascientific situation, seriously presenting the result of his study to the audience. However, the work is not devoid of mockery. Identification Office is a humorous reflection on prejudices, simplifications and social stereotypes as well as the imperfections of past and present methods of forensic work.
