When the cards are spread, a marvelous picture appears!
If we had Marvel heroes' artwork here, it would be amazing, right?
The case keeps the texture of the card spread to match the name. Embossing the overlay creates a real texture.
The Marvel Avengers logo is designed to be completed by attaching three cases together. Also, there are three different types of pictures depending on which direction you spread.
Artwork is designed to show up magically, and there's even more novelty created with a total of 54 chapters -- the "six cards" include individual artwork by Marvel. The back design matches numbers from 1-6, so you can match the cards you're thinking of.
