I had a desk like this once. I found it at a thrift store in Manhattan and rolled it back to my apartment on a dolly. I sold it a few years later because I'd outgrown the style, but I could have taken another approach to freshen it up, like Natalie from Natty by Design did:
The shock of green is really fun, and certainly makes a statement. Love the desk? You can buy it in Natalie's shop for $295.
