North American Club Nintendo members can now rejoice, as you can now grab a giant AR Card for your Nintendo 3DS for 200 Coins. The card is approximately 28.5 inches long by 18.25 inches wide. The two-sided card features both the question block and Mario. It is delivered in a folded state, but the crease is said to not affect the use of the card.
