That certainly helps! Yes, we do have TYRIAN listed in our PID, under #177. The cup sure looks different than the plate, at least from the angles of the photo. I was able to find the referenced book on the internet (available from Thriftbooks) and I took a copy of that photo that I will send to the PID directors: hopefully it will be a clearer shot that will upload better, and it can be used as comparison. Thank you for the information!
