This Monkey King aka Sun Wukong and John's other recent head marbles represent the pinnacle of John's artistry up to this point in time, and honestly, it's hard to imagine him taking it even further than this, because these marbles are soooo mind boggling. However, John never stops, so no doubt he'll find some still higher level...but it's just hard to fathom, ha. Look at that detail in the monkey king's head made, soooo freaking wild!! This guy also has incredible eyes that glow green under the blacklight from the UV. It has a gold fumed backside which is the first time I've seen this in one of John's heads. This is wildly amazing glass that will blow people's minds for centuries and millennia to come! Get Sun Wukong at the center of your collection, ruling over all! Signed with John's Kanji signature.
