Here's a new (at least to me) online shop that specializes in old-tyme style toys for kids. They describe their "Tree House Kit' as follows: Tree Fort is a magical woodland wonderland where all of our miniature dolls and animals want to live. Each fort is completely unique, as they are made from the smaller salvage branches of hazelnut and alder wood trees. So there's a green component to this as well. The other thing that is more modern than old tyme is the prices. The 34-piece kit will run you $149 while the 59-piece kit will set you back a whopping $269. Talk about your green component...as in cash.
