Eddy's Magazines are very valuble magazines. They are "one of a kind," as said by Eddy. They were given to him by his brother, and are prized by Eddy himself. He would probably give an arm and a leg for them in any kind of situation involving them, and maybe even 3 of his adult teeth. It's no secret to Edd and Ed, as they know how valuable they are to him, and Edd blushes at the hearing of them.
