Nesting Dolls

We got two wooden nesting dolls from by Grandma. I wasn't really expecting for my boys to play with these, but they love them. Westley was with Grandma today, so here I was just helping Will  one-one-one as he worked intently on them.
Why don't they make toys like this anymore?

The little piece are a choking hazard, but they both really enjoy playing with them
