This hobby isn't new, it's playscale miniaturism. It is a combination of dollhouse miniaturism (with or without the dollhouse) and scale modeling. It's population and accessories just happen to hail from both the green and pink aisles. Barbie established the scale in modern times (which is why it is sometimes called Barbie-scale), but, when Joe became a civilian
--and got hair!-- with the advent of his Adventure Team (or earlier in individual collections), the scale became irreversibly co-ed; it
married the two camps. Prior to this, most adult collectors were polarized into military & fashion (or domestic) miniaturism, largely along gender lines.
