I have read about all white piano keyboards in articles on music theory and instrument construction. I believe the first organ keyboards crafted centuries ago may have had all white keys but the more sensible white and black design was adopted soon afterward. I do not think anyone today is making a keyboard like this.

Maybe the black keys are hidden behind the top panel?

Maybe that's not a keyboard at all. Maybe Maki Maki is playing the xylophone without the sticks. You know, because Maki's Maki.
