Ab die Post! (1987) card tray

Card Holder for "Ab die Post!" (1987)
This is a card holder for the board game "Ab die Post!" (1987): https://boardgamegeek.com/image/1601362/ab-die-post
It is not related to the different game "Ab die Post!" (1996), which should not be confused with this one.
The holder fits both postal item cards (Postsendungen) and event cards (Ereigniskarten).
I printed three of these holders, which works well for organizing the different card types during gameplay.
The holders are sized so that they fit inside the original game box, while still leaving enough space for the game board to be placed on top.
