Welcome Dave. You have one very lucky nephew! I have made several toyboxes over the years but toy boxes are all that mine are -your toybox is a work of art.
I must add a quibble -It's too bad that you did not utilize the "real" Winnie the Pooh as drawn in the A. A Milne books and not the Walt Disney version. Sorry to bug you about this, but the "Disnification" of many things including Winnie the Pooh is a pet peave of miine.
