Simpsons Comics #230 Sketch Cover- Bart Simpson (Matt Groening)

Simpson's Comics #230 Sketch Cover by Simpson's creator Matt Groening. At Comic Con International 2016, Bongo Comics had a rare convention exclusive at the show, around 100 of these sketch covers were sold with Matt Groening's sketches being one per person sold to fans. Matt drew most of them with around a dozen or so of the other covers being drawn by various other Bongo artists such as Bill Morrison (I was lucky enough to get at the end of the show) and Jason Ho. When asked if they would eventually sell the blank sketch covers to fans through stores or conventions for other artist to sketch on, they said no. Extremely rare original sketch cover comic. I'm looking for other sketch covers from this Simpsons Comics #230 if you want to sell or trade.
