You're all probably right. I'll blame it on presbyopia - I didn't put on my reading glasses and take a close look at the image. But it is curious why they used a photo - Alpha seems to use real paintings for their early music CD covers. (Including, oddly, a couple of Holbein drawings for two CD's of the Bach unaccompanied violin sonatas and partitas.)
