I've been continuing the Gengar theme in our Leaf and completed another project this week. First I found 2020 (Had to match the car right? ) Gengar cards in holo and reverse holo. Then I paired that with an acrylic 2 card display case and mounted it to the high voltage disconnect door in the back seat.
I think it turned out well, and the wife likes it too. It might be a bit silly but it adds a nice accent to the back seat. The sun catches the foil at the right angles too which is cool.
