Mobile users can add these stickers to their photos by adding photos to tweets within the Twitter app and tapping the smiling face to enter the stickers menu. From there, users can choose from eight new stickers in the World Series category.
Twitter stickers act as visual hashtags, meaning that a user can tap on a sticker on a picture to view other public pictures that contain the same sticker.
