I was reminded of my white whale today when I happened upon an image of it.
It's a mid-century teak desk bar with drawers on the left and a lazy Susan behind the cabinet on the right. I've never seen the front of this bar desk combo, and I don't even know anything about it (maker, etc), but I would buy it sight unseen if I ever happened upon it again. I've only seen it twice (never without a sold tag already on it) and I know I may never see it again.
I have (arguably) one of the best mid-century desks already in my home, and I have no place to put another desk, but like any mid-century furniture enthusiast, I would find space and reason to capture my white whale if I ever got a real chance at it.
