Poncho-Wearing Pikachu (Mega Rayquaza, Stamped) - 2015 Japanese Promo - MC Business Card - PSA7(MK)

POP 1.  The 2015 M Rayquaza stamped business card Pokémon promos were part of the Pokemon Center 2015 Poncho Pikachu Campaign, which took place in Japan from December 12-31, 2015.   To acquire one of these cards, customers had to make purchases of 2,000 yen or more during the campaign period and were given a chance to receive two randomly selected cards from a total of eight options.  The M Rayquaza "stamped" business card is considered a secret rare card and was very difficult to obtain during the promotion. The back of the card even says "Super Lucky."  

This is the only graded copy of this card in existence with the stamped, gold checkmark in the bottom-left corner.  Thus, PSA added "MK" to the grade.
