Mukatolini's Litographs are a series of lithographs made by the renowned artist Mukatolini.
Appearance
The only known lithograph, the third in a series of 50, is a collection of abstract shapes of different colors on a blank background. The author's cursive signature is located below the picture, next to its serial number, and it is nearly as big as the picture.
Using Gyo to spot "residual aura", Gon and Killua find one of Mukatolini's limited-editions works (3/50 in its series) at the Bull Market. They buy it for 9 11,000 after outbidding Zepile and then resell it at a pawn shop for 9 150,000
