For Wreck it Ralph, the theater could place the little pixelated character stickers anywhere it wanted. In the case to the left, they chose the snack counter. You can also see they did clings for more than just Sonic, there's a pac man ghost & Vanellope too. Above appears to be some sort of theater made but sort of -fan-done-also wall promotion. The Sonic's sure not official, but the rings spell out Wreck it Ralph. Modern Eggman
is also used, unlike the classically styled sticker. It's sort of a mashup of stuff, but if someone at the theater was a big enough fan to make it to promote the movie, it's interesting to see.
