This is written by the artist David Martin for me, Peri Charlifu. Peri Charlifu is a master potter and extremely talented craftsman and artist.  Years ago, I was a member of a family of potters who owned Marshall Pottery, a seventy-year old business distributing their products worldwide.  I’ve seen the accumulated skills of potters who have perfected their craft over forty years or more, and in Peri, I recognized the same level of mastery and more. Peri knows his market.  I’ve been a contributing artist at SF conventions for over forty years, and I recognize someone who not only knows what fantasy fans like, but is able to tailor to the craft show market as well.  My personal favorite is his work based upon the writings of H. P. Lovecraft.  I’ve purchased over thirty pieces for my home and always look to see if he’s done something new along these lines. Peri routinely shows more than a hundred pieces at SF conventions.  It’s easy to see that not only is he talented, but is also fast and reliable.  I’ve seen art show demonstrations in which Peri has constructed huge and beautiful creations in less than an hour.  To me, there is no better mark of professionalism than an artist who can create something in front of a room full of spectators.

Steve Wahl
Long time fan and progenitor of fans. My home has bookcases for interior walls and all are overflowing. Simply loving the newest in SFF books and media. Reading 4 novels concurrently at the moment. Have been a fan since late 60s. Also was scientific and systems software developer for 43 years after I came out of school as an archaeologist – from punch cards / punched paper tape to thumb typing and Alexa. Ended up accidentally with six patents. Finally happily retired with more time to read now!
