Great painting! But it is 100% Afghans. This is not the Uzbeks and Turkmens from Bukhara.
Cuprum, you are - as always - technically correct. These are the Afghan horsemen I commissioned Empress to make as part of their 'Jazz Age' range. However they are, IMHO, the best sculpts for the period and general area (done by the blessed Paul Hicks), and work for me as a compromise. I might get round to commissioning more accurate sculpts one day....
