Two different types of cards were inserted into the hobby boxes of 2006 Allen and Ginter as a box topper. Each box would contain either a postcard box topper or a N43 box topper. The post cards measure approximately the same dimensions as a standard US postal service post card. The card fronts feature a black and white picture from a location that would be associated with the player. The card backs feature a short message from the player, hand written by the player with a signature. The "stamp" of the post card features a small portrait picture of the player.
