可動人偶?!

Seen this in TST's 1881 Heritage once. Where real people (mostly men) took photos of dolls (apparently called 可動人偶) against real background. Reason that 龍友 dont use real people as models is apparently (i) real models cost money (ii) time is less flexible, vs a doll (iii)easier to snap photos inside small spaces and still get the "full effect" of a studio shoot. How strange...
