An blue wood puzzle block that was in my grandparents attic that we used to drag out just to prove we could put it back together. It was a childhood toy of my mother and aunt.
When you take the block of wood apart, it becomes a set of furniture. The toy is probably 100 years old.
Unfortunately there has been damage over the century. The chair is being held up by a table fitting under it — the two share each other’s missing legs for support.
