I think someone really loved Susan to have hand-crafted such a wonderful toy step-back cupboard for her. I found this lovely piece in the Strasburg, PA area.
You can see all of the incredible features; the upper doors open.
The bottom opens up.
There is also a bin that opens up. A tiny hook and eye on the side holds the lid up.
Tiny knobs and wooden door closures that rotate into place.
Overall the pieces stands 24" high.
