The Pulp Ricktion tee design is for Rick and Morty and Pulp Fiction fans.
The concept is funny and true to the Rick and Morty characters. The Pulp Fiction characters of Vincent Vega and Jules Winnfield (seen above) are replaced by Rick and Morty. This is one of the funniest and best versions of the numerous Pulp Fiction parody/mashups out there. Though the art work of the characters doesn't appear to be original at all, like a straight rip from the show. It looks good. After all, the characters were not created by LavaLamp so not all of the creative credit can go to him obviously.
As for the artwork, this one also adds a bit of color and references the devices of Rick and Morty instead of Vincent's and Jule's guns. However, while Rick's Portal gun does produce Green portals, Rick's laser gun that Morty is firing should be Red or Blue to stay true to the show's episodes. It's nice to see a cartoon version of the Pulp Fiction scene.
While this is the Pulp Fiction pose it is definitely more of a Rick and Morty fan tee.
