From Jonathan Edwards College. I am told that this image is derived from Edwards' beer tankard. It also appears on the JE college tie.
Now you know.

Badge and Crest
The badge worn upon the College blazers is a red apple surrounded by a green serpent. It recalls the Reverend Jonathan Edwards' preoccupation with the doctrine of original sin. It is borne aloud and not upon a shield. It was devised by the first Master and Fellows, and designed by H. Dillington Palmer B.A. 1924. It forms the silver head of the ebony mace of the College, hanging in the Master’s Office as the symbol of authority.When a more formal device is desired for use on a decorative shield, banner, a letterhead, or a title page, the coat of arms is preferred.
IThe coat of arms described in heraldic terms is: ermine, a lion rampant vert (green). This coat is a simplified form of the arms used by the Reverend Jonathan Edwards himself. He had it engraved upon the most valuable piece of silver in his possession – a tankard purchased by him with money present by his congregation in Stockbridge. The tankard, now in the New Haven Historical Society, was made about 1757 by Zachariah Brigden, silversmith, of Boston, who had learned his art as apprentice to Jonathan’s kinsman, Thomas Edwards, The arms which it beards do not indicate the color of the lion. In the arms of the College the lion is green, the color adopted by the College some years ago. – c. 1938
The green rearing lion symbolizes courage and purity of heart. Its crimson tongue and nails exhibit willingness to pursue its goals with passion both of speech and strength. The veil of white that surrounds the lion symbolizes the Grace of God, and the other eleven residential colleges are represented by the eleven black daggers (a later modification of the crest).
