I thought I recognized it, and I turned it over to make sure my guess was correct. Yup: Pottery Barn:
It's still sold in their catalog. This ledge retails for $65, before tax:
It has been knocked a tiny bit on one edge:
And it's dusty, but that's hardly a problem:
I've asked Lovely Daughters #1 and #2 if they'd like it, and if so, in its original medium-brown wood color?:
Or maybe glossy white. Because now that I have mastered the fundamentals of sanding and spraying, I'm on a tear!
And anything white on gray walls looks so pretty.
