From Team Fortress Wiki
The Philateler is a headwear item for all classes that is awarded the following day to the player that purchased the most Map Stamps in a given day. It is an oversized top hat covered in stamps with a magnifying glass and a folded map stuck in the band. The hat is large enough to cover the top half of the player's head, giving off a team-colored glow.
Possession of the hat is not permanent and is limited to the player that purchased the most Map Stamps in a given 24-hour period. This potentially allows the same player to possess the hat multiple days in a row if the player can maintain the most Map Stamps purchased. Paint, custom descriptions and custom names on this hat, as well as its level, will carry over to the next owner.
