Not exactly a duplicate image, especially given the second is just someone dressed up like the first, but they are very similar.
Also it's not really the trope, which is "the implication that a character who dislikes a particular thing is secretly a practitioner of that thing", like that in Seven Samurai the samurai that hates peasants turns out to be one
or that in Who Framed Roger Rabbit Judge Doom is turns out to be a toon
. Not sure how "this is implied" and "this is true" jive with each other, but the article has examples of both.
