A rare thing about Yury's works of wonder is that the MAN comes before the ERA. With facial expressions this appealing, the concerned period / subject is only secondary in significance, and rightly so.
Figure modelling can meet different needs of different people. To revisit / honour history. To convey a universal emotion. To test one's knowledge of shapes and colours. Yury's is a graceful mix with slightly more weight on the second need, the way it appears.
