Snape's Bias

"Ron didn't answer; Snape had just awarded Hufflepuff a penalty because George Weasley had hit a Bludger at him."

- Card description

The Snape's Bias adventure card is the forty-seventh card of the Quidditch Cup Expansion of the Harry Potter Trading Card Game.

The illustration on the card was made by Patrick Faricy, and it depicts Severus Snape signaling a penalty against George Weasley during the Hufflepuff vs. Gryffindor match in the 1991-1992 school year. The illustration is the only visual depiction in canon of Snape refereeing the Quidditch match, since this was not featured in neither the films or video games.
