Zephery Hughes, afaik, more or less went to ground some time ago due to combination of health problems and want/need for the financial stability, and while still active on the scene today, noticeably less so than, say, two decades ago (understandably) - his presence manifesting basically in drawing random shite for shits and giggles, and posting it in private gallery.

The one and only mention of this particular thing I could find with cursory search is a post in old fur.announce group back in 2000. And while I am pretty sure it is complete, the order of pictures is most probably differs from the printed form. Not that it matter that much, given the nature of the product in question - but still.

Regardless, the Artist:
