Looks clean, but some of those keys look quite shiny (might just be the camera flash).
You probably want to include a photo of the label on the underside, and another with at least one of the key caps removed to show the switch type and that there isn't a ton of hair and crumbs beneath (also showing off the doubleshot keys at the same time. One showing the connector at the end of the lead wouldn't be a bad idea either.
If the photo's representative, then I'd be tempted to say very good condition.
Just stick it in the marketplace...
