Laserline CD 90 CD Storage Rack - Black Hard Plastic - White logo.  Holds 90 CDs.  Has wall mounts on the back.  It also can be stacked.  In nice condition.  Dusty. 

Notice that this is the earlier SQUARED rack, not the later ANGLED rack.  The squared ones stack much more securely on top of each other, and are much more sturdy and desirable.
