All four of them sing out 'splendid craftsmanship' to me. The one for your grandson is the one that I would be most inclined to try to build myself. I am curious how you went about crafting in the bumps on the deco side inlays. I'm also curious about the joinery you used on the outer portion of the top. Panel construction is an aspect of woodworking that I am itching to explore. By that I mean making a panel by constructing a 4 piece frame that encloses what ever the inner portion of the panel turns out to be.
