In Homestuck after John became consciously aware of the graffiti he had unconsciously done to his movie posters he sought out a way to use alchemy to restore them. He theorizes a way to subtract captchalogue codes from each other and harlequin figure from a defaced Ghost Dad Poster producing three items, one being the painting at the cost of 425 Mercury Grist, a reference to the $425 that Hussie had to spend to obtain the tangible painting. It can be seen later in the story when Andrew hanging above his mantle.
In real life the painting was painted by "T" and currently belongs to Andrew Hussie. On December 17, 2007, after having spent several years obsessing over the painting, Hussie launched a fundraiser in order to raise the $425 needed to buy the painting. The fundraiser met its goal on January 7, 2008, and Hussie had gained physical possession of the painting by January 18.
